Just as a fyi for spell designers in case some unfortunate future dragon gets this or its derivative.
The spell has a minor and a major flaw
Minor flaw: making the dragon stand still above towers gives defenders time to catch up - they can hammer, shield and sword and cue more hammers, even load strategic supershots. Thus when you uncloak you get annihilated.
Major flaw: the explosion on emergence removes disabling effects like sand and vines and lockdown. This essentially makes the spell rubbish.
If someone wants to put this spell on a dragon in the near future, make the emergence explosion the same spell algor’s roar so that it debuffs and doesn’t unsand.
Consider making the dragon have 1 sec immunity on emergence.
