How do I calculate what a successful reflex DC save when trying to dodge against the flaming sphere?


1 Answer 1


The DC for a saving throw against a spell is 10 + the spell level + the caster's casting stat modifier + any other bonuses, such as the spell focus feat . This is stated in the class descriptions of each class that can cast spells. Flaming Sphere is no exception and I can't see why you'd think it would be.

For example, if the spell was cast by a Wizard with 18 Int, the DC would be 16 (10 base + 2 level + 4 int).

    \$\begingroup\$ +1 but I'd add: +any other special modifiers from feats, class abilities etc. Foe instance a creature from Plane of Fire might have a racial feature that says "+1 to DC of any spell with the [Fire] descriptor. Granted, these are more rare for evocation type spells than other schools but they do exist. \$\endgroup\$

    \$\begingroup\$ @Ben-Jamin I always consider "plus any other modifiers" to be a given but I'll edit that in. \$\endgroup\$ Apr 25, 2015 at 14:52
