Enchant scrolls for weapons and armor: what is safe and what is not

How weapons, armor and jewelry are enchanted: the safe levels, what happens on a failure with ordinary and with blessed scrolls, and links to the scrolls of every grade with the monsters they drop from.

Weapons

All the weapons in the game are enchanted with weapon enchant scrolls (no-grade weapons and the weapons of Olympiad Heroes are not enchanted). With ordinary scrolls any weapon is safely enchanted to +3. If you go on enchanting with ordinary scrolls and a failure happens, the weapon will break into crystals. If you enchant with blessed scrolls, in the case of the same failure the weapon will not break but become +0 (all the enchants are reset). So people often enchant with ordinary ones to +3 and then finish with blessed ones.

The scrolls by grade: S, Blessed Scroll: Enchant Weapon (Grade S) and Scroll: Enchant Weapon (Grade S); A, Blessed Scroll: Enchant Weapon (Grade A) and Scroll: Enchant Weapon (Grade A); B, Blessed Scroll: Enchant Weapon (Grade B) and Scroll: Enchant Weapon (Grade B); C, Blessed Scroll: Enchant Weapon (Grade C) and Scroll: Enchant Weapon (Grade C); D, Blessed Scroll: Enchant Weapon (Grade D) and Scroll: Enchant Weapon (Grade D).

Armor and jewelry

All the armor and all the jewelry (including epic jewelry) are enchanted with armor enchant scrolls. One-piece armor is safely enchanted with ordinary scrolls to +4, everything else to +3. If you go on enchanting with ordinary scrolls and a failure happens, the thing will break into crystals. If you enchant with blessed armor scrolls, in the case of the same failure the thing will not break but become +0 (all the enchants are reset). So people often enchant with ordinary ones to +3 (+4 in the case of one-piece armor) and then finish with blessed ones.
