I disagree with this, while yes this is annoying, it also forces you to take important tactical decisions:
1: do I wait a few turns for the spot to disappear and then resurrect
2: maybe I should cast that rain spell to get rid of the fire before attempting to resurrect
3: mmmh, or should I delay the turn of my chars with the healing and/or resurrect spell so I can heal the resurrected char much quicker/in the same turn
4: Oh crap, I know that enemy has a fire/earth/... AoE attack, I have to remember to cast my support spells accordingly and heal my chars quicker to account for some of the possible AoE dmg in the future
...
I think this adds a great extra challenge to the combat and forces you to prepare for a fight (potions/resurrect scroll/...) and to think and adapt while you are in the fight itself.
That's a reasonable perspective, but on-the-spot resurrection is about more than AoE spells.
1: The game encourages you to resurrect ASAP because of the XP penalty for dead characters, and faffing about delaying a few turns trying not to kill enemies will generally end up getting more guys killed.
2: You don't always have the means to disperse particular AoE elements. Additionally, that doesn't solve the problem of on-the-spot resurrection making your new character vulnerable to attacks from anything - melee and ranged attackers as well, not just spells.
3: That's a reasonable tactic to try, it might help, I can try... but resurrecting already means probably having to save up AP for a turn and not healing yourself with some item, which could get you killed. I can try experimenting with this and seeing how effective it is, though.
4: Currently some of the damage is so high that you can be one-shot killed from full health. There's no way to prepare for that.
I don't mind the XP penalty and resurrecting at partial health, but while resurrecting is encouraged by the XP penalty, it often seems somewhat useless as the character is just one-shot immediately before they can act.
The Teleportation spell can move a body, and a dead character linked to one that uses a teleporter pyramid will move, as well.
Is that new in this patch? I should check. I know that it was not working last patch. That would certainly help with this complaint if it's working now.
