Spell Messages
 

A couple of issues. First, when I'm in a group and an ally casts an offensive spell at a mob, I see the message twice (i.e. orc centurion singes as the burst of flame hits them, or whatnot). This may not be exclusive to groupmates, but it doesn't happen with my own spells when I'm soloing. Second, when a monster dies due to a dot or a damage shield on me, I get a message as though the dot is being reapplied (an orc warrior has been poisoned) or in the second case, as though I just cast the damage shield on the mob (an orc warrior's skin sprouts thistles).
