What?? I don't even have the skill for seeing elements, and I haven't built any structures in the Castles (and besides, the damage from elemental chains isn't added to the main damage in the logs, but appears as a separate line) (moreover, at that point I only had one native Castle, and I captured the other two later, in search of the "Explosion" spell)... there's a clear 1782, and with a 5+ luck chance, this probability is slightly higher than 0.075 (either you made a typo, or you mean a 7% chance of Expert Luck triggering?? less than one hit out of ten??)... and why are you giving me mathematical formulas? Just play the game... there are approximately 3 out of 5 hits with luck... And the argument has reached a dead end, because I'm telling you how it PRACTICALLY works in the game, and you're trying to force your theory on me... the difference in approaches is really obvious...
