Instead of using the standard attack to ignite the burning stacks, ignite the stacks by casting BURNDAYRAZ on another monster. Consider using the Wizard, as he begins with the BURNDAYRAZ glyph in his inventory. The glyph will also cost 1 less mana to cast, and each fireball adds two stacks of burning instead of one.
Easy "Supreme Slayer" achievement
Play the Northern Desert as a Gnome Sorcerer. Prepare the Glowing Guardian altar at the Church. Explore and kill some monsters to reach level 2. Find all five glyphs, three mana boosters, and three mana potions on the map. Convert all the glyphs except for BURNDAYRAZ into mana potions and purchase an extra mana potion from the apothecary. Also purchase a random item from a shop to convert it for an extra mana potion. You should have ten mana potions in total. Find the Boss, Aequitas the Warlock, who has 159 HP. Repeatedly shoot fireballs and drink mana potions when needed. If done correctly the boss should have 1 HP remaining. Go to the Glowing Guardian's altar, worship him, and choose the Humility boon to reduce your hero to level 1. Hit a random enemy to ignite the burn stacks on the Boss.
Experience
To earn extra experience, defeat monsters that are at a higher level than your own character. When multiple enemies at different levels are encountered, consider defeating the ones with the lower levels first; killing the one with higher levels may cause you to level up and earn less experience for the lower level kills. Because leveling up complete restores your health and mana, try doing so immediately before facing a Boss.
Races
Each race has various strengths and weaknesses, as well as unique stats. Humans and Dwarves are best suited for melee characters. Elves are recommended for glyph based characters. Halflings and Gnomes are good for classes that benefit from health and mana potions. Orcs are the best race for getting experience points. Playing a Goblin may present a challenge, as they are not suited at anything in particular.
Spell Glyphs
Some classes start with a specific spell glyph in their inventory. However all classes can use them after they are found in dungeons. Attacking enemies with spells is usually safer than melee attacks. However you may need to have mana potions if you use them frequently. Your maximum mana limit does not increase when leveling up. However, finding the three mana power-ups in each dungeon will increase it slightly.
