The spear might be the first triple skill, but it's still pretty lackluster. It's stinger+/assault or stinger+/strength (assault+defender) on FLB. 15/15 isn't too horrible I suppose.

The other two doesn't seem to have a FLB, but has assault+/a new buff that seems to affect one specific character (in the 3rd/4th slot). The cane gives enthusiasm for 4 turns on the char in the 3rd slot, while the orb gives 10t regen to the char in the 4th. Depending on your team I could maybe see these being useful for very specific things, but otherwise... meh.
