Nnn.... I dont think the bomb disrupts soul stars. Like I dont think proxxy even knew about soul stars anywhere in the underside, what she used was probably just a more normal EMP bomb, or something like that. Also aren't cleared levels just levels that you know, we've cleared and gone though, or has there been something to support that apparently cleared levels are a bad thing?
Also eehhhh. Soul weapons seem to be uh, not directly in it for the damage, I think. I think that their weapon forms are more for the secondary effects that they hold. 1d4 is not great levels of damage. Funny though how ciro's seems to be capable of more damage than the others, probably signifying that ciro's is stronger, maybe?
I mean If I felt like it I would probably look at all other symbols for every other soul star/ sibling and look at possible meanings from those, but eh.
I'll give you an easy one: Look at the Astral Influx and the Illborn Exchange.
Awwww..... Work? Fine. Illborn exchange has an arrow, most important thing on it's 'star' form's menu is the up and down arrow. Considering that there is a slot for illborn, and that the other slots can take Items I think, means that the arrows are probably to do a conversion or exchange, down for illborn to something, up for stuff into illborn maybe? And the astral exchange. Well that's got maybe... A flame symbol, or a spirit symbol? Considering it seems to move US around, the dead so our perspective is focus'd on someone else, I guess its to do with spiritual movement. The sword form, is pretty much a mystery to me I guess, maybe testing out its secondary move will provide answers, maybe.
(+1 to putting slog in illborn exchange and pressing arrows randomly.) <- Probably not a good idea if we're planning to make Electrically themed ally from slog and stuff.
