Ask Deykari about how good his saves usually where when he fought my poorly trained shaman vs Enell , and my first pinned shammy ever. Saves are a VERY important part of it. And after playing Vasraema and Krondrin, Shamans are my least enjoyable fight, because a smart shaman lands a mal, cures to full, lands a mal, cures to full, unless he is firing them off at will.
Invoker races.
Faeries cant defend very well at all.
I pinned and cabaled three faiere invokers. They are pretty good, with the right eq you can pump the hp to 1100 +, but, they are weak conned get sick easy and dont parry worth a damn.
Their mana may regen faster than any, but their hp regens slower than any. Heck a drow has to die like 20 times o get down to a faries con, heh. 
That is why i love Avian 19 STR and CON. I can go from dead to full health in 4 ticks, as long i have eluded persuit.
Curative consumables help a lot in that respect if you stock up well. Though there's only so many you can carry, and they do get burnt up fast.

Deykari needs to explore more.
Goods have a serious advantage when it comes to stockpiling a particular curing item.
However there's only a couple of Invoker races that can actually use it thanks to a strength restriction, if it's the one I'm thinking of.

The two main nonrare cures i use both have pros and cons, but the easier to acquire one (good only) can only be used with 19 str or better, a bit of a bonus to avians. That said i suppose the more time consuming to collect is actually better overall if you can stay well stocked on them. If you can afford the rare slot getting a certain scroll can be worth it as a good also.
Nope, the one I am thinking of can be used by anyone. I used to use it on my faerie bmg (never pinned or went anywhere with her)
edit: and this one is not rare.
