Light Spear, Gungnir & Asgard Hat

Better than being assisted by Odin's washboard abs? I don't think so.

So do latents transfer too? Cuz I’ve got GrOdin with rainbow resists, if I turn him into this will the latents stay to his Reincarnation weapon form? And then will they also show up on whatever I assist with this weapon?

With the HP+500 awakening, this card gives better HP to the base card than Grodin Split Ult.
This is good for an HP lover like me.

(instead of +500, HP awakening still gives +200 HP in NA server. But I think it will be updated to +500 one day.)

If I get a dupe grodin, I'm gonna go for this evolution but until I get the dupe I'm gonna stay away from this one as I occasionally find use for this evolution of grodin in no RCV dungeons.

Dear me, this is really neat. I'd finally have an actual reason to use Grodin to assist his dragon self.
The problem now is when I'd get another creation jewel...

so does the base have to be max leveled before reincarnating?

I can't seem to add this guy as an assist monster to 3499. Can that even be achieved?

This might sound stupid, but what would be the criteria for a good monster to be a base for this?
