ToME: the Tales of Maj'Eyal

Not sure if this is a bug or a really good strategy, but with a level 5 (4 due to mastery) phase door you can sense enemies, then target them with phase and put them wherever.

Just use corrosive vapor somewhere, sense and phase an enemy into it.

Actually, you don't even need to see them with sense, as long as you target their square with phase you can teleport them whether you can see them or not.

Also you can target enemies from farther away than you can actually teleport them.

My opinion isn't very relevant, but this sounds more of an abuse than a bug to me. (That and it's rather clever!)

There are some rather clever uses for phase door - I hid the merchant in one of the rooms before fighting the bandits.

I encourage such creative play

You can also target slighty further around corners than you can see. Sense becomes really useful if you have manathrust to approach enemies from the right direction.

Chain lightning makes a poor mans sense, and I use it as my first attack to check if there are other enemies.
