I'd leave that up for the DM of course :) And yes, one could omit the safeties such as being usable only outdoors and not being able to enclose things in rock-strong cloud. Then they become dangerous indeed.
Great article. I also like the idea of treating Mind Control as basically a form of illusion. It has the disadvantage of requiring notes/private chats/etc to implement fully though.
Willingly playing out the effects of mind-control should provide some form of reward to the player, even in the case it leads to their character's demise. Perhaps some form of boon on their next character.
This is pretty cool, but from a hard SF perspective, evaporating a non-trivial region of existence is going to release immensely more energy then a little bit of hawking radiation.
Maybe if the collapsed matter/energy is shunted somewhere else it would help in the whole conservation of energy thing. Maybe these weapons create nasty explosions in another dimension. Might attract the wrong kind of attention...
The second effect of obliterating a fixed radius of reality if in an atmosphere would be a massive shock wave as the vacuum collapses. This would resemble an explosion whose energy would depend on the volume of the destruction.
For fun I threw some numbers at it. A 1 km radius sphere has a volume of 5.24×10^8 m3. A vacuum has VERY roughly 2kJ of energy per m3. So, ~ 1x10^9 kj - which is roughly .2kilotons. A good boom. Go to Comment
