How to play

• Click or tap an enemy to focus fire. Use the Rune Burst button, or focus the field and press Space or Enter, to burst the focused enemy cluster. Change spells and buy upgrades in the sidebar. P pauses.
• The keep casts automatically at your focus target, falling back to the nearest enemy. Rune Burst recharges in six seconds; a burst with no target costs no cooldown.
• Clear wave 2 to unlock frost slow, and wave 5 to unlock storm chains that pierce armor.
• Gold upgrades apply to the current expedition. Essence buys permanent spell power, burst strength and keep health.
• Boss waves arrive every five waves. Restarting an expedition begins at the wave after your highest cleared boss.
