Um. Personally I found an idea of variable encumbrance... strange. Maybe use variable St-based damage bonus instead?

Per se the encumbrance varies as a result of Strength varying.

All strength bonuses apply, where applicable, I'd assume.

Copied from duplicate issue #2258:
Walk commands (w#) will be interrupted in case burden status changes from burdened -> not burdened or not burdened -> burdened and maybe in other transitions too. This can be annoying for level 25 chaos knights who receive 1d(# of corruptions) bonus in strenght that changes every turn (and are carrying enough stuff to be burdened only on some lower rolls).

Some possible solutions:
- Add configuration variable to toggle interrupting walk on burden changes (similar to walk_carefully, but for interrupting walk on burden changes).
- Only interrupt walking if burden status changes to higher than it was when you started walking (for example if you were strained, you'll continue walking as long as you are unburdened, burdened or strained, no matter how often it changes during walking).
- For all or only level 25+ chaos knights: Don't interrupt walking if burden changes due to strength changing, except if one becomes overburdened.
- For all or only level 25+ chaos knights: Don't interrupt walking if burden changes due to any reason (rotting, si).

Would solve the problem, but I don't think it's an optimal solution, because typically only advanced players edit configuration variables.

Insufficient, because if your CK starts walking with St 20 and gets down to 18 (and Burdened) on the way, you probably don't want the walking to be interrupted.

The best solution IMHO. Fixes the problem completely and doesn't affect the rest of the game much, because it's very unlikely that this will cause interruptions in situations different from the CK class power.

Also good if it's only applied to CK's. For all classes it would be too much of a change IMHO, although it would do if solution 3 (and 4 for CK's only) is hard to implement.

I'm not sure how sufficient or insufficient this would actually be. In theory walking could be interrupted at most 3 times (unburdened -> burdened -> strained -> strained!) but in practice I think it would be interrupted only once or not at all in almost every case. Surely this would still be minor inconvenience.

Can't we just get this configurable variable, if it is set to current behaviour by default it doesn't affect anything. At least then for us wanting to play Chaos Knights, we can set the variable when we reach level 25. Well I would always set it once I'm past the very early game or not carrying sis. Although with stats dropping somewhere between Hungry and Very Hungry, maybe a problem. Can't you just set an extra interrupt for those satiation related stat decreases.

I believe sami's third solution is optimal. I don't want configuration options out the wazoo, they should be kept as minimal as possible. Since this is a problem specific to level 25+ CK, the change should be applied just to them and I think it should be the third solution (though I'm fine with the fourth as well).

I also nowadays am inclined to say we should start putting brakes on configuration variables, the list is already getting on the lengthy side. So, option 3 from sami it is in my view also.

Option 3 has been implemented.
