Because you've been so helpful I feel like I should be giving you some kinda reward, like what a lot of QMs do for Omakes.
Also no one has any suggestions for spells?
It's fine, I haven't done all that much yet. Maybe if I'm going to be doing this kind of thing more often.
I've also seen several quest's balance be pretty much broken by rewards, so I'd advise you to be rather conservative with those in general.
As for spells, well, judging by that teleport we pulled, we can already do that, and we have experience in Space magic?
First off, the basic spell categories that we should have covered if we should have covered if we want to fight: Offense, Defense, Movement. Our presumable specialty also lends itself to various support roles, such as Battlefield Control.
Offense: Our axe, which propably doubles as a gun. Beyond that, we may want some long-ranged spells if we can, but I'm not sure if we're capable of folding space into harmful effects such as cutting waves, piercing projectiles, or damaging areas of warped space. Another more feasible avenue should be folding the space around projectiles, in order to make them faster and alter their trajectory, so we can make them guided or let them turn around corners, for example.
Defense: Most valuable would be space folded into a barrier, which, again, may not be feasible. However, warping space to make us harder to aim at, or even to redirect projectiles away from us entirely should be well possible.
Movement is the big one; For Space, both flash-step like effects and tactical teleportation, as well as strategic-range teleportation like we already demonstrated, are definitely dead within theme.
Battlefield Control: Warping space to inhibit enemies and help allies, changing the distances between points and possibly even influencing the local gravity vector.
Stealth: Distort space to redirect light around us and break up our outline, making us harder to see.
I can imagine more esoteric effects, but those would require that instead of simply warping space, we're able to influence parameters within certain spaces, such as temperature. But that sounds both too abstract and rather OP, so I'm going to disregard those.
