Can Kinkou Monk's effect trigger when you only have 1 other character, or does it require 2 targets to enter the chain?

Ruling: After the errata, Kinkou Monk now says "up to" so it will always enter the chain, even if you only have 1 or 0 other units to buff.

Nuances:

• Before the errata, the effect only entered the chain if you had 2 other units available to target
