There are several problems with Chromatic Orb.
1. According to the dialogue bar, the 1st-level version of the spell sporadically (i.e., ~50% of the time) subjects the caster to a saving throw (see attached screenshots). This does not preclude the saving throw subjected to the spell's target. Also, though I've tested for this phenomenon numerous times, the caster never seems to fail this erroneous save. The save is applied only when casting the 1st-level version of Chromatic Orb; caster levels 2-7 appear unaffected.
2. The 1st-level version of the spell is not applying its Blindness effect to the target upon a failed save. The feedback string is not displayed in the dialogue bar (e.g., "Firbead Elvenhair- Blindness"), nor do they suffer from the effects of Blindness. The secondary effects of higher-level versions of Chromatic Orb appear to apply correctly.
3. If the target of the spell makes a successful save, all
effects of the spell are negated, including damage, in contrast to the spell's description, which states that the damage is applied even on a successful save. This applies to all caster level versions of the spell.
4. If cast at a neutral NPC, a successful save will result in the NPC not turning hostile, a likely consequence of successful saves erroneously negating all effects.Expected behaviour:
The 1st-level version of Chromatic Orb should not subject the caster to a saving throw, and should correctly apply the Blindness effects to the spell's target upon a failed saving throw. Targets who make successful saves against the spell should still be subjected to the spell's damage. Targetting neutrals NPCs with the spell should turn them hostile.Games affected:
BGEE, BG1/BG2 (to varying degrees).Notes:
These problems look to be holdovers from vanilla BG1.
In BG1: The caster is subjected to the erroneous save at 1st level. The 1st-level Blindness effects are not applied. All effects are negated upon a successful save, though this was intentional in BG1 and is consistent with the BG1 spell description. Successful saves don't turn neutrals hostile.
In BG2: The 1st-level Blindness effects are not applied.
These bugs are still present as of Build 0629.
