(He, Him)
Returning, in a moment of ennui. I actually like a Constitution (Athletics) check here, to represent the more skilled climber spending less energy on the climb. They know how to avoid muscle strain and position themselves for rests during the climb.Why not each hour of CLIMBING a PC has to make a CON 10 check or gain a level of Exhaustion? The DMG says it as far as swimming, and that's the same movement penalty as climbing, so should the penalty of DC Con 10 per hour apply too?
Generally, I have been thinking more about passive and variant checks, which is a mild surprise because at the outset I felt quite skeptical about them. But imagine that part of why we needn't check for a straight climb under no pressure is that it is Easy / DC 5 and even the feeblest character can make a DC 5 check passively given time to retry and no likelihood of falling. Very good climbers might enable others to passively overcome a DC 10 climb, by taking disadvantage to give them advantage, or doing something that a DM felt earned a group check. Could a Strength (Stealth) check make sense to represent climbing with care not to disturb rocks or make a fuss? It feels to me like there is untapped nuance in the mechanics that could be unpacked into richer, yet still highly consistent and relatively simple, skill uses.
