According to the PHB, Dwarves get a +2 to saves against spells and spell-like effects (IIRC). If a Wizard casts a spell like Command on a Dwarf, it seems obvious that the +2 would apply. What about spells like Lightning Bolt, Magic Missile, Web, Fireball, Melf's Acid Arrow, etc. where there's a physical element brought into play? Would the +2 apply to saves against these spells because they fall under the phrase "spell like effects"?
