Something else which I see nobody has suggested yet - Combat Reflexes. It seems a bit of a waste for giants, considering most have low Dex and anyway are unlikely to get a bunch of AoO opportunities per round, but the feat has a sometimes overlooked benefit which synergizes very well with giants - it allows one to take AoOs while flatfooted. So even if the PCs surprise some giants or beat others on initiative, if they have Combat Reflexes they'll be able to take AoOs while the PCs move through their threatened spaces.Odysseus said:Awesome blow sounds like a good idea.
Thanks for everyones suggestions.
Garnfellow said:Daniel R. Collins had a similiar notion a few years ago and built regressed versions of the true giants, moving them back to their 1st edition HD. I updated his work to 3.5 and posted it on my website:
I'm using these stripped down versions in my homebrew conversion of G1, G2, and G3 and so far I've been pretty happy with the results.
