If you read through the link I provided and look at the datestamp in the URL, there wouldn't be any need to conjecture about Magic Reflect. Cool screenshots. I won't say I'm glad that something there could kill WWs but... it's a refreshing change of pace, lets put it that way. I was too dead at the time though to notice that Semidar had life drained the piss out of everyone's pets.
I can confirm that many pets were harmed during the dragon spawn in destard the other day, too. I lost one, and I think I was the tamer there that lost the least. Someone lost like four dragons and his mare. Spawns really aren't all that tamer friendly. It's hard to get large numbers of mobs off your dragons, caster mobs here seem to retarget pretty intelligently, and many of the spawns have monsters in the later level that lethal poison. Tamers seem to be strongest in the early phases of the spawn, while bards take over as better later in the spawn.
