The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
From what I gather, no... because the seed requires a "divine focus", which might not be a holy symbol but something "religious". (Can you spend "points" to remove that? I dunno. I haven't looked at the ELH in a long time.)
Certainly lore from some settings supports allowing wizards access to the seed. Many archmages have a tower that will heal them if they teleport there, perhaps due to Contingency plus Teleport. (A wizard could easily stock up on healing potions, but those don't help if the wizard arrived unconscious...)
