1. If you use the gate spell to summon multiple outsiders whose (each one's seperately) HD doesn't exceed your caster level, can you control them? For example a 17th level wizard uses gate and summons two horned devils, can he control them or not?
2. When a character dies with temporary negative levels (for example from multiple energy drains) and then raised, does he still has the temporary negative levels?
Why?
because it reads like you tried this at the table... and it didn't go so well.
No, the first one came up in a conversation about an upcoming encounter in the game i run and the second came to me when i was reading the astradaemon monster for an upcoming encounter as well.
