Sometimes attack is the best defense!

This is a "guide" for playing with melee classes, a tactic that I like to call "incursion". This is super effective against hordes of enemies, and it can easily exterminate all the enemies inside an area.

1. Start escaping the enemies like any other character. Invest on defense to reduce the damage taken and try to concentrate the enemies on a small area.
2. When they die in that area their drops will remain close, this will accumulate some health potions in that spot.
3. Get to full health before attacking.
4. Start with small incursions, the enemies will agglomerate together, don't try to cross all of them, try to cross a small slice diagonally.
5. Getting hit speeds up the attack, it will make you attack multiple times during the "incursion".
6. Heal! After passing inside the enemy army you might need to recover some health before the next attack, take your time, health to full hp and then attack again.
7. Know your enemies. Some enemies hit much harder than others, try to avoid the heavy attackers. 

Have you tried this tactic?
