[Nyaa]

Q299
Is it intended that Chameleon (lens) [Light] doesn't grant ability to hide without cover or concealment?

Q300
And that Earthquake Stomp [Brute] doesn't scale with user's size?
What does "all valid targets" mean btw? Does it trip allies too?

Q301
Consider Sage with Unarmed Training, Spear Dancer, Morphic Weapon (used to graft a spear), Rubber Ki, Attune With Light.
Does it work at all? If it does, what's the reach of grafted spear at level 8? 15 to 35 ft?

Q302
Does Enhancer Sage need to pay a ki point to use (enhance) talents for Wis mod rounds, and/or concentrate on them?

Q303
Do sages retroactively gain combat, enhance and blast type talents when gaining new esoteric training packages at 8th and 16th levels?
