ToME: the Tales of Maj'Eyal

Hello.

I just saved his ass.
But the dumb merchant stepped on a square with a dagger and that is something I am in dire need of.
And he refuses to move.

I've had this happen too

This should still be fixed, but for now it can be sometimes circumvented:
Phase Door level 4/Swap style skills
Knockback effects
attacking with weak attacks (such as unarmed) until he is hostile, and chasing you. If you can escape with him still alive, you get the reward.

These aren't ideal, and are easier if you are a wilder or Divine class with heal other abilities.

k. Here is a patch to fix this. You can only talk to the lost merchant once before fighting the assassin lord and once after defeating the assassin lord (we don't want him to be overly chatty). Also, you will only be able to move the lost merchant after the assassin lord is dead. This way, players won't be able to easily cheese the battle by moving the lost merchant somewhere safer before they fight the assassin lord.

Patch is tried and tested.
