concentration_check
Calculate the concentration saving-throw DC after damage, and optionally resolve whether concentration holds by including the d20 result and Constitution modifier.
Instructions
Compute the Concentration saving-throw DC when a concentrating creature takes damage: DC = max(10, damage // 2), capped at 30 (SRD 5.2.1 p.179). Optionally pass d20_result (+ con_modifier) to also resolve whether concentration holds. Returns data {dc[, total, success]}. The caller rolls; srdcheck folds.
