Spellweaving

Spellweaving, otherwise known as combined skills or combos, can be created by either dragging one skill onto another one or by pressing the spell weave hotkey (default: R) then the first skill hotkey followed by the second skill hotkey. Creating a combo skill makes it behave as if it was a freshly dealt skill, meaning its fade out timer is reset. Combos can be discarded by right clicking or dragging them off screen like normal skills.

Trivia
When introduced, the combat method in Shroud of the Avatar was explained as a deck of cards and Spellweaving was explained as playing pairs of cards as a combo.

The first player sourced spellweave idea was from Arkah EMPstrike and is the Summon Skeleton Mage spell. He also contributed the Evaporate and Sacrifice spells. These three spells were all introduced in Release 19 by Chris Spears.

Note: Combos marked with an asterisk are spells that can be cast without using a combo if you have them in your deck and skill tree.
