Grenade lunge

Grenade Lunging
This is a relatively easy trick, which can kill pesky Brutes or Elites very easily if done right. It is similar to Sword Canceling.

You need:
 * A sword
 * At least one plasma grenade.

Lunge at an enemy, then, right before you hit them, throw a grenade. The plasma grenade will always land on them. Immediately jump backwards, or the explosion from the grenade will kill you, too.

''Note: this trick is not recommended against larger groups of enemies on higher difficulties. On Legendary and Heroic, you should use this only against groups of one or two enemies.''
