Riptide

Battle instructions:
Can train two dragons at once in the Mire or lower.

In the first battle:
Prep turns:
1) Meditate (to gather breath)
2) Haste (to increase speed)
3) Rally (to increase strength)
4) Defend (or rally a second time to increase breath by a bit)
Fight: Eliminate the enemies (starting with melee enemies then castors to minimize taking damage)

All future battles:
Prep:
1) Rally
Fight: Eliminate as above

If you get low on breath and start a battle against only caster enemies, proceeded as if it was your first battle.
If you get low on health, you can choose to use a health potion if you have only one enemy left and two turns (one to heal, one to eliminate and finish the battle)

Refresh the page if:
1) The fight is against a boss
2) The first battle has four enemies (can be done, but is difficult)
3) You miss Eliminate and run out of breath
