I've not played much with the ring of necromancy but it does sound like a fun tool if your undead actually die (explode) when they are supposed to...
If you gave a bandit an iron dagger poisoned with weakness to frost before reanimating it, then you have an amusing kamikaze corpse!
Do they explode the second they take damage or do they explode when they run out of HP?An average corpse is capable of doing a hell of a lot more damage than 50pts during their short life cycle, it seems that overall the ring nerfs your necromancy...
Darn it I just sold that ring yesterday! Would of been so easy to test! Unfortunately I just looked on youtube and that is not the case. They explode when hit the 1st time.Here is the link.
Hmmm actually I have an idea. Just get that ring and get a staff of revenants. Then just find a skeever or whatever and keep it raised. With sumoner 2/2 you could just sit back infinitely raising the same body for 0 magicka.
Or... I wonder if this could work with the aetherial crown? If you had 20+ bodies and a chain reaction was possible that would be nasty!
