**Mining or disintegrate from inside a mine will not result in the 20 entrance slope, it instead connects to the 2 lowest tile corners.
**Any item, corpse, player, mine door or altar in the way will result in 'Item in the way' error.
*Disintegrating reinforced walls chances are very low – 2% for a 50 power cast and 10% if you manage to cast a 90 power spell which is hard enough for a difficulty 70 spell. This goes up to 25% at 95 power and 50 percent at 98%.
**In PVP Off deed reinforcements will have a much higher chance to break when using the disintegrate spell.
