Similar spells

The 24 spells that run on the same game code as this one. Only what changes between them is shown.

The 24 dragons are four tiers (power 50, 100, 150 and 200) for each element; within a tier they differ only in element, runes and texts. All of them touch with the same 8 px radius: a bigger dragon does not hit wider. The 200 tier waits 121 ticks (2 s) before acting, where the others wait 2, and lasts as long as the 150 tier for about the same MP.
