You teleport away from danger into new danger

Ring of Flare in ToME 2 was similar. Very overpowered, so long as you had time to set up the jump gates in advance.

[Therem Harth]

Mindcrafters also get that at high levels. It's kind of ridiculous but very fun.

Controlled teleport is one of the most powerful abilities in any variant that has it. I've no doubt that would also be the case in Vanilla. Precise positioning is vital to effective combat, and right now the only way to precisely position yourself is to walk, which has a host of interesting consequences that controlled teleportation would completely obviate.

...hence my judgment that giving mages controlled teleport in the feature/magic branch pretty much makes up for anything they've lost.

Nethack has no-teleport levels to prevent teleport+teleport control from being used to completely bypass difficult challenges.

How about semi-controlled, so that you can give a direction but not distance and game picks up random spot in cone-like area in that general direction?

Even that would be very powerful, exact control is IMO too powerful.

Possibly. Have you tried any of the classes on the feature/magic branch, Timo?

No. I haven't had much time to play anything lately. I play my favorite dwarf priest when I feel like it, but I have now played one char for about two months and have got almost half-way to dungeon, that's how much I have time playing.

One idea for spellcasting I have is to make variable casting times. MM could take 1/4 turn in high levels, alter reality 20 turns (if not disturbed) and so on. A bit like ranger shooting arrows, you could cast single target spells multiple times / turn if spell is low level and you are high level. Preparation spells could take longer times. You could even reintroduce invulnerability if you make it cost a lot, last only few turns and make casting time 20 turns. No more infinite invulnerability.
