Stay on the path of blood and bodies to avoid being poisoned (except for one part where you have to jump across).
If you have your creature, you can summon it as well to help there. In general I found it better with a ranger head than warrior, and best with a mage head.
What level are you? If you have a save before entering, you can always reload and come back later. The temple can be done after reporting back on the bandit camp location (though finish off any open quests you got there before talking to Louis).
On the PC you can use the F1-F3 buttons to switch weapons.
On the Xbox you can equip a bow and melee weapons (hold a button/pad direction down for a couple seconds to assign an action/skill); whenever you use an attack or skill that requires a certain type of weapon, your character will automatically switch, if needed.
Playing a warrior I assigned X melee attack, A range attack, Y Rush Attack, B whirlwind, left Dragon Stone, right Dragon Morph stone (both after getting the battle tower), up Heal (level 1 comes in handy) and down summon creature (after getting it).
