(i) seems like you've come up with one more edge case where Upheaval is preferable to Disaster Area. Very well:
4)There are hellions lurking behind LOS and are threatening you without seeing you.
This situation requires a few unlikely factors coming together: you know where out-of-sight hellions are, you're not more pre-occupied with other monsters, and the hellions present a very urgent threat that cannot be better handled by other means like repositioning or closing a door and waiting for them (you're cornered at low HP?) And hellions are among the few mid/late-game threats that
might be one-shotted by Upheaval.
(ii) yeah there's a chance disaster area could miss completely, namely if you're doing it all wrong. But so what - it's not like you use
only never-missing attacks, like fireballs and cloud spells. Most attacks in crawl can miss, and that doesn't mean they suck. The possibility of missing completely is a "real concern" only if the target can die in one Upheaval - and this falls under edge case #1 in OP.
advil wrote:(iii)...tossing it off casually (vs upheaval) increases the likelihood that this will be impossible.
no, tossing off
upheaval "casually" is the greater drain on your piety, since you need to use it so much more to get anything done. That's my whole point.
(iv) The existence of a massively inefficient yet seductive option is a problem. Take TSO. You can't just rely on summons - they're not sustainable. Now imagine if TSO had a 1* ability to summon a holy pig, and it cost 1/2 the piety of summoning a divine warrior. Well, it would be OK, maybe even OP, for helping TSO worshipers get through the early game. But if people kept using that ability all throughout the game, preferring multiple swine over a single angel or daeva,
that would be a problem.

huh? what I'm doing is documenting a problem in Qazlal's design. I even
refrained from giving solutions.
