I'm having trouble with adding a custom spell ingame by commands,
can't seem to figure out why.
I'll give you a look of how the spell looks in the Creation Kit:

help "tri-force"That will give you the FormID of the spell to use. It'll be something like XX003320, where XX is the variable prefix of your mod. It will NOT be 02. Then you should be able to do:
player.addspell XX003320to actually add the spell to your Magic/Powers menu.
