Other possible combinations that might prove useful (of course, all of these are subject to GM approval.):Here's one combination example I got off of Palladium forms. Need extra P.P.E.? Ley Line Time Capsule plus Energy Sphere. Cast Energy Sphere, fill it up, throw it in the time capsule. That thing will last for months!
Magical-Adrenal Rush on Snowfall's 10-headed hydra?
(Re: Energize. I didn't know Energizing non-tattoo spells was a thing until I read the description. Now, the cost is kind of ridiculous (12 + you have to cast the spell you wish to energize all over again) so I don't think I'll be taking that one. I guess the tattoo-Energize has me spoiled! =) )
Time Slip + Dimensional Portal = See ya!
Featherlight and any weight-based tattoo involving travel. =)
Ooh. Timeslip + Featherlight + Dimensional Portal?
Black Sun tattoo (stealth and short-range travel) + Aura of Death (hides caster from infrared/thermograph)? Add Invisibility (Simple)?
The pondering continues. =)
