Bump.
To Nickolas' question, it's not done, but I find this a great idea, a weapon bash dealing no to 1-2 damage, but knockback for example to use against the basilisk grab. Basilisks would have to learn to get behind humans. The bash would naturally have a repeat long enough so lisks do still have all the chances to kill people, but skilled users of the feature would gain a small benefit. Large aliens onwards from marauder, perhaps even advanced basilisk would be immune to the knockback.
This seems to have got a lot of support too, and you can count me in that group.
