as i understand it, items will stack, and will stack with various spells, but 2 spells of the same line WONT stack. for example, you can have two augs with regen I, a regen 2 aug, an item with built in regen 2, and (for this example) Regrowth, for a total of (1+1+2+2+15) 21 points of regeneration. AA regen will stack with those too, and a spell feom a different line (like the regen a shaman gets for being in bear form) to increase your regen more. as with other spell effects, spells in the same line, say Regrowth and Chloroplast, wont stack, but bard songs should. this is how it seems to be working for me so far, as a lvl 55 shaman, with AA Regen III, a Regen I aug, bear-form, and Regrowth, all at my disposal...i dont do any of the parsing or whatever it is people do to completely validate things like this, but it seems i can usually Cannibalize III all the time, and let my regen take care of my health. of course if i start getting attacked, my regen cant cover that, and if i am not paying attention to my health, i can find myself REAL low on health all the sudden. like in an intense LDoN, you finally get a break, have been castiong regularly, and your Regrowth wore off in a fight...drops regen to about 1/3 what it was, and i need a lot mopre mana as soon as possible...i glance up, and "WOW!! im at 20% health, i coulda canni'd to death!! (boy i woulda felt dumb!) time for a stoicism!" anyway, thats my 2cp. let me know if any of what i have been doing doesnt work teh way i think, please

Regen items stack with any of the combinations of them, just like FT.

For example:
Regen3 + Regen4 + Regen5 = Total regen of 12
Regen3 + Regen3 = Total regen of 6

It is rumored that there is a Regen cap of around 30 or 35 like the FT cap, but i'm not sure if that is still true or not.
