[(BGEE, BG2) bug] Grease

CamDawg · July 2012

Grease lasts for 10 seconds, regardless of your level, and had an incorrect casting time, icon, and range to boot.

This will correct those errors and extend it out to level 20.

@CamDawg
It does not really matter, since the vanilla spell only has 1 ability header, but the loop across existing abilities always reads and writes to/from the first ability, regardless of the value of the index variable. (Fixed in v10, btw.)

CamDawg · July 2012

Oh yeah, I see it now. You're right though, it won't affect this patch.

KeithS · July 2012

Adding...

Nathan · July 2012

Verified that this has been integrated internally, and should be present in the next build.

Avenger_teambg · July 2012

Confirmed fixed... tentatively.
Well, there are now 20 headers, i guess the script ran

Damned i be if i check all effects in all headers

Confirmed Fixed:

20 bloody Spell abilities for each level now... Grease just got a lot more slippery...

Spell description:

Grease (Conjuration)
Level: 1
Range: 10 yards
Duration: 3 rounds + 1 round/level
Casting Time: 1
Area of Effect: 30' x 30' square area
Saving Throw: Special

I'm assuming the duration shown in NI is in sec then, and 1 round = 6 sec. That's the formula that makes the following work...

Duration set as such for Effects #0, 1, 3 in each:

         Dur Rng CastSpd      Icon
Level1:   24  30       1  SPWI101C
Level2:   30  30       1  SPWI101C
Level3:   36  30       1  SPWI101C
Level4:   42  30       1  SPWI101C
Level5:   48  30       1  SPWI101C
Level6:   54  30       1  SPWI101C
Level7:   60  30       1  SPWI101C
Level8:   66  30       1  SPWI101C
Level9:   72  30       1  SPWI101C
Level10:  78  30       1  SPWI101C
Level11:  84  30       1  SPWI101C
Level12:  90  30       1  SPWI101C
Level13:  96  30       1  SPWI101C
Level14: 102  30       1  SPWI101C
Level15: 108  30       1  SPWI101C
Level16: 114  30       1  SPWI101C
Level17: 120  30       1  SPWI101C
Level18: 126  30       1  SPWI101C
Level19: 132  30       1  SPWI101C
Level20: 138  30       1  SPWI101C

For once though we've got a spell fix that makes a spell more powerful rather than less. ;-)
