I've tried to balance these more or less to PHB spells. Anyone see massive abuse potential? They are for a specific campaign so I am not too worried about the balance, but I don't want my party wizard going mad with power either.
Note that situational gravity is melee, hence the rather potent effect.
Tholre's Curious Bubble - Wizard Attack 1
Encounter * Arcane, Radiant, Implement
Standard Action, Ranged 10
Attack: Intelligence vs. Reflex
Hit: Target is surrounded by a rainbow-coloured bubble of light, but takes no damage this turn. At the end of your next turn, the bubble contracts for 1d8 Radiant damage. See Secondary Hit.
Secondary hit: If the target tries to move or shift (not push/pull/slide) after initial damage is inflicted, the bubble bursts for 2d8+Int modifier radiant damage. If the target remains stationary, the bubble bursts at the end of your next turn for 1d4+Int modifier radiant damage.
