Q: just want to double-check a certain interaction: a while back when asking about Miryoku no Shima granting other personalities Kensai, I recall that the validity for the second weapon is only checked when equipping it, and never again after the personality loses Kensai at end of turn.
Alongside that logic, if I use Blessed Dojo to increase a Shugenja's Chi by 2 (happens when they're targeted for the first time by one of their spells) while I've got Wataru Sensei (Shugenja cannot have more spells than they have Chi), will excess spells be discarded at the end of turn when the bonus Chi disappears, or is that also only checked when equipping spells? (side note, while writing I checked the spells in my deck and only 3 copies of 1 of them targeted the equipping Shugenja, so I removed Blessed Dojo, but if I ever rebuild or go for a pure shugenja Dragon deck it would be good to know)
A: "Cannot have" is different than "A Kensai Personality can attach two Weapons if neither of them is Two-handed.".
Kensai is checked while attaching, Wataru's trait is constantly checked. Less Chi - discard redunant spells. Unofficial answer: kempy_nezumi, "Sun and Moon #rules-questions", 14 Jul 2023
