Popping out of hide we can get Fires of Gehenna cast
Hide: This is a tough one for me, as I can see both pros and cons with it. First, it doesn't include our Last Chaos Gold familiar. So if you have it summoned in PvP you'll want to dismiss it before using Hide at all, or else your location is pretty much given away.
Moving while hidden (which applies to all but rogue archetype classes) is another Stamina drain. So steal thing into casting range can mean A) no Spell-weaving until our Stamina regens and B) No sprint if we get into trouble.
Both of those things said the element of surprise can and will help us win fights we otherwise might not. For example: Popping out of hide we can get Fires of Gehenna cast on a target 2 or 3 times before they ever hit us with a melee weapon, giving us a definite advantage.
By the time they reach us, our absorption shield is enough to deal with a first combo - from there it's a careful balance of dodge / cast and knowing when to do which. So yea, that's a tough one for me.
Bandaging: Of the characters I made, some I maxed this skill and on others I didn't. To be honest I preferred putting the points elsewhere, since we have low HP and "Rest" will regen it extremely quickly. That's just my take on it though!
