Post any interesting house rules or modifications, additional feats etc you are using for T20 here.
I´ve changed the gravity adapation feats.
Now, there is Heavy-G/Low-G Adaptation, which allows the character to operate without penalties in any substantial gravity - basically, any body with a size digit of 1 and above. (There just aren´t enough worlds with Heavy-G to make Heavy-G Adaptation on its own worthwhile, especially if it rules out Improved Zero-G/Low-G Adaptation)
The other feats have been changed into Zero-G/Micro-G Adaptation, plus the Improved version thereof. "Micro-G" is what you have on bodies of size 0 and S, Zero-G is exactly what it says on the tin. Also, the different "paths" of gravity adaptation feats no longer rule each other out, since they are no longer "opposite" but different developments.
Also, since T20 uses Dexterity instead of Strength for melee attacks, I have come up with a feat to replace Weapon Finesse: Brute Strength. You need Strength 13+ to take it; it allows you to use the Strength modifier in place of the Dexterity modifier with all melee weapons except the foil and any electrical shock/stun weapons (too brittle), and (since melee weapons aren´t as important in T20 as in D20, so that alone wouldn´t be as powerful) in place of the Charisma modifier for Intimidate skill checks.
