#715 closed bug (fixed (in master))

Use a better algorithm for magic devices fail rate

Reported by: takkaria Owned by: magnate
Milestone: 3.1.2 beta Keywords: player


An idea might be to plot the existing rates on a graph of player level vs item level first.

Oh, and display it in item descriptions too.

New discussion here:

My next job is to create a list of all activatable devices/effects together with their depth (which is currently their difficulty rating), assign putative difficulty ratings, and list the base device skill of each race/class combo at each clev. That should enable a fairly easy attempt at a new algorithm. I feel a spreadsheet coming on.

  • Milestone changed from 3.1.1 beta to 3.1.2 beta

The spreadsheet is at, but neither of the algorithms is satisfactory. High level magi are too good, and high level warriors are not good enough - so I think this means we need a quadratic approach. Postponing to 3.1.2 as agreed with Takkaria.

From #angband-dev for posterity:

(17:28:46) takkaria: I think I'd be happy capping at 1 or 2% fail instead
(20:42:37) takkaria: yeah, since AIUI, activation is basically a mechanical or thought based process
(20:42:53) Magnate: So no effect from wounds or blindness, small for poison, fear, berserk, and slightly more for stunning then confusion at the top. Ok?
(20:44:28) takkaria: yeah, I think that works

(with small positive effects from Bless and Heroism, and max fail of 95%)

(in the same conversation it was agreed that confusion should increase min fail to no more than 25% - though of course this does not help with aiming)
