What are the nasty sustains on bosses?

[rangerjeff]

Lvl 42 Marauder doing fine on Normal, except now twice in Orc Prides vs end of the room guardians I've taken surprising amounts of apparently reflected damage, died once to it now.

How do I know when a baddie can reflect damage? And what can I do to not kill myself in the process of killing them? Haven't played all the classes yet so I'm unfamiliar with the names of talents/sustains which may be dangerous to my health... Whatever the name of this one was (damage came back as light) and any other particularly nasty sustains to watch out for would be great information to have.

And what tools in general are available to deal with them... well, besides unstoppable... I suppose I should have had it up but I try to keep it in reserve rather than lead with it.

Thanks!

silver rune/rune of reflection, can give you reflective shield.
golem's reflective skin works the similarly, except still taking the damage himself, and instead of total reflex, he reflects % of the taken.
then there is displacement shield from the conveyance tree, is a shield that reflects all damage to a specific target, instead of the attacker.

not quite the same but, cunning/tactical has a talent that let's you throw an attack of opportunity, every time you miss a melee blow.

... there might also be some chronomancy magic doing it.

and then there are some "when hit" damage.
phantasmal shield does a lot of light damage whien hit
acidic skin of the reaver, and a simmilar talent for the oozymancer splashes the attacker in acid.
chants and hymns do damage to the attacker.

Yeah, guy had Phantasmal Shield, hurt a LOT. I did 1700+ damage to him, he reflected back 1400+ to me. One and done.

Tooltip will specify if the target has any retaliation damage. If this is high, don't use a multi hit talent.
