Assuming you enter the spells area of effect and end your turn inside this area on the same turn. Does it trigger twice?
A creature must also make this saving throw when it enters the spell’s area for the first time on a turn or ends its turn there.
Not a native speaker, so I am not sure whether this means you make a saving throw when entering and when ending your turn in the area, or that you have to make one saving throw when one of this happens and only once.
It seems a bit overpowered when it triggers twice, dealing 8d10 damage is ok for a 5th level one-target spell, not a lasting multi-target AoE spell (DMG p.284)
