When gizmoduck uses his active and shares is armor as SP with Nick Wilde, the other allies are not being benefitted with Nick’s newly gained SP, which he shares 35% with allies.
For some reason the status effect doesn’t show, but it should still be there
Maui should be activating his skill significantly earlier do to the increase of skill power (true damage) transfered from gizmoduck via Nick, but this is not happening. Nick does transfer the skill power at the start of battle, which can be easily evidenced by the increase in damage caused by maui’s knockback skill. But after gizmoduck increases nick’s sp, maui should also be able to use his white skill quite earlier. This doesn’t appear to be the case in the tests I performed.
Because he only share core SP, and it’s permanent thing as long he lives, that’s why icon doesn’t appear.
I don’t think he’s supposed to share only core SP.
It doesn’t make sense to be that way. Nick’s mechanic is very clear, you need to build up is lemming rush and this grants him more damage and skill power. His red skill allows his allies to also scale up with him by granting more of the SP he gains from additional lemmings. This should also be true for any additional skill power he is receiving. If there was another hero that could also share skill power with allies, there could be an issue of endless increase in skill power due to an eternal loop. But this can be easily avoided by limiting the number of iterations between Nick’s skill and the one from this potential SP-sharing character.
