Chapter 1
You must use the weapon triangle. Do not let Boyd and Titania fight swordsmen. Do not let Oscar fight axemen. Ike can fight anything. Visit the nearest house with Ike to get a steel sword. Have Titania kill the leader.
Do not expose Boyd and Ike to too much danger. In any "Finish him" situations, where the enemy has less HP that your might (MT), use Ike or Boyd to kill them. Have Oscar attack Myrmidons and Titania Fighters and Bandits. Use Ike to go to the first house (next to where you began) and Titania to go to the other houses. Allow Titania to fight the Boss.
Chapter 2
Move Rhys to the map's edge. Move the others around him. Stay like this until Titania arrives. When she arrives, move around and take out bandits. If she is too hurt to fight, switch with Ike. Keep this up until they are all dead.
Defend (surround) Rhys until Titania arrives, then go for a full charge with Titania in front and Oscar behind her, and after that Ike and Boyd. Make sure to keep Rhys in the very rear
Chapter 3
Do not visit this time. Take out pirates with Shinon and Gatrie. Then, take Titania and Ike on the ship. When there are a few pirates remaining, talk to Marcia (or someone similarly named) with Ike. It will be useful later. Then, use Ike to take out the captain.
Have Ike go left, Titania go right, and Shinon and Gatrie in the front. When the left and right road are secured, rescue Ike with Titania and move to the ship. A Pegasus Knight, Marcia, arrives. Have Ike talk to her. She then flies off, but you will get her back.Then, charge in at the Boss.
Chapter 4
This is difficult, but keep up. Make a barrier around Rhys and Soren. Put Shinon and Gatrie in the front and Ike and Titania on the sides. Wait until they lessen their numbers, then charge at the rest.
Put your pointer on an enemy and press [A] to see where that unit can go. Do this to all the nearby units and make sure that Soren and Rhys are not in this area. Then, wait and counterattack the approaching units. Then, charge in with Shinon and Gatrie.
Chapter 5
Make a wall to protect Ike ,Soren and Rhys: <PRE> | Ike, defend spot | Soren | Rhys | empty | Empty Empty | Empty | Empty | Shinon Gatrie | Boyd | Oscar | Titania </PRE>
The locations between two "|" positions is a square. If an enemy like an archer is two spaces in front your wall of men, use your cavalry (Oscar and Titania) to kill them. If anyone is directly in front of your men, use Soren and Shinon to attack them. Keep doing this until the map is clear.

Chapter 9: Marcia
In Chapter 3, make sure Ike talks to the Pegasus Knight at the top left of the screen before she gets killed. Do not worry too much; she dodges a lot. She will mumble something about repaying a debt and flies off. If you did this, later in Chapter 9 she returns about two to four turns into the mission. Make sure Ike talks to her and she joins you. She is not the greatest, but with a bit of work turns into a very reliable unit. Plus, she flies.

On chapter 22, Solo, there is a group of priests that are taken hostage and used as bodyguards. Instead of killing the priests, including the head priest, shove them out of the way. The ability Smite will be useful in this battle. Mordecia the Tiger Laguz has this ability, and in the last battle if you raided all the rooms of their treasures, then you should also have another Smite ability. Use these to knock the priests out of the way and make sure not to stand next to the ones with light magic; they will damage you or you will kill them. If you make it all the way through the level without killing any of the priests, the head priest will reward you with the Ashera Staff (Staff-S Wt-4 Range-total, restores all HP to all allied units, as well as restoring their condition to normal).

Level manipulation
Throughout the game you get bonus experience to use inside the base. After you use it, you can save or reset the game. In battles, get all your characters as close as desired to a new level, without actually reaching it. By doing this, you can save bonus experience when giving those characters a level up. For example, if they have 99 experience points, you will use 1 point to gain a level, as opposed to 100 when they have 0 experience points. If you can get multiple people to need very little experience points, you can effectively manipulate the stat gaining for everyone. You can reset the game if the stats you want improved do not gain anything. In this manner, you can effectively make any character however desired. You can possibly manipulate any character to max out any stat desired, if you can gain every level at the Base. Save after each individual character gains what you want them to.
Triangle attack
This is a special attack that can be done with Boyd, Rolf, and Oscar. All must be able to use a bow, meaning Boyd needs to be a warrior and Oscar must be given the ability to use bows. Form a triangle around the target and choose one of the brothers to do the attack. Note: You must see two conversations between the three at your base. Make sure to check the "Info" option frequently.
Holy Knights Triangle attack
This is the same as the Three Brothers Triangle Attack; you must have Elincia, Tanith and Marcia all together. Place them in a triangle formation around an enemy and command one of the units to attack. Note that the three units must be able to use swords. This attack can only be performed near the end of the game. Check on "Info" at base often.
Deadly Assassin
When you get Volke, do not use him close to enemies and make sure you have him when you pay him after Chapter 19. After hearing the story, he will ask if you wish to hire him in case you go berserk. Agree to him and he will say "Now I can reveal myself", and will change classes to an Assassin.
Stat control
When you are in the base, you can save your progress then reward units enough experience to level up. If you do not agree with the stats they gain, reset the game and level them up again. You can do this as many times as your Bonus Exp will allow. Make sure to save your game when you get stats that you want to keep. The process is somewhat time consuming, and you use a lot of Bonus Exp, but it is very helpful for building up almost invincible units.
Glitch: Mystery option
After completing the game under the normal or hard difficulty setting, go to the Extras menu. Then, go to the bonus maps. Select the first map, and when asked "Is this correct?" select "No". Then, press [B] to leave the bonus maps screen. Go to "Illustrations" and there will be two Fire Emblem: Path of Radiance options. However, you cannot select the second option though. To get rid of the second option, exit the Illustrations screen, go to the Bonus Maps screen, leave the Bonus Maps screen, then go back to the Illustrations screen. The second option should be gone. Note: This must be done before you add Fire Emblem, and Fire Emblem: Sacred Stones to your game.
Glitch: Wrong name
Throughout the game you will notice that Ike refers to Elincia as Princess Crimea, instead of Princess Elincia.
