I recalculated the formulas for effects 116 to 118 (cleric pre50 symbols), this seems to be closer from lucy :
in spell_effect.cpp, row ~1950
Code:
case 116: // ryltan (31-24+1)=8 (158-94)=64
result = ubase + 8 * (caster_lvl - 24); break;
case 117: // pinzarn, approx (41-34+1)=8 (307-224)=83
result = ubase + 11 * (caster_level - 34); break;
case 118: // naltron -> seems good, (525-406)=119 119/(50-44+1)=17
result = ubase + 17 * (caster_level - 44); break;
