Restore is less useful on people with less maximum health in game

Casting heal/speed on assassins can have the effect of getting on their good side. Don't quote me on that, though. I prefer to warhammer gold hide behind large men.

Take the rewards that people give you. Refusing waters just wastes time and it's not like you won't need them. That's not to say that you should humor jerks who offer you g46 for free. (You wouldn't accept, right?)

If, for various reasons, you are attempting to heal someone in a monster (clipping problems), try clicking on the edge of their calves and back, or any other part that's sticking out. If that doesn't work, kindly tell him (or her) to back up a tad (that is, if he/she is expecting a heal from you).

Remember that Restore (lv.42 skill: heal 25% health instantly) is essentially a Heal 2 that can target others. A quick combo is Cure 2, then Restore. This will boost most lv. 40-50 knights up by 50% instantly. Restore is less useful on people with less maximum health.

A sae hak (g40 healing stick) will help conserve your mana. Be prepared for strange looks if you fight with this, like I do. Holding one of these is also a signal that you can heal/speed/revive, even if you cannot do one or more of these.
