At first I thought Mortalbane was very straight-forward. An example I read is a warlock casting Chilling Tentacles. Enemies take 2d6+2d6 cold damage from the effect, plus they take 1d6+4+2d6 bludgeoning damage if grappled.
Then I looked at Summon Swarm. At first I thought it was obvious that it would work well with Mortalbane just like Chilling Tentacles. But then I started wondering: Does Mortalbane actually work with conjured creatures? The more I thought about it, I'm worried that Mortalbane only actually affects Chilling Tentacles because the spell is actually a damaging spell - the 2d6 cold damage. I started to worry that it would not actually work on other conjuring abilities at all because they are not damaging. The ability being cast is a summoning spell.
So I guess the full complicated series of questions is this:
- If Mortalbane is used on a spell-like ability to conjure a monster, does that monster then do 2d6 more damage with everything, or does the use of Mortalbane have no effect because the actual of conjuring spell-like ability does no damage?
- If conjured monsters do not get bonus damage, then will chilling tentacles only get 2d6 bonus damage from the cold aura, but the grapple attack will just do 1d6+4 per the spell?
- If conjured monsters do get bonus damage, does Mortalbane also then apply to secondary effects? Does a swarm of bat's 1 damage/round bleed becoming a 2d6+1/round bleed, or does a swarm of spider's 1d3/1d3 strength damage poison into a 1d3+2d6/1d3+2d6 strength damage poison for a total of whopping 6-30 possible strength damage?
