-> Loner Bonus: If one or more artists own less paras on the collab-drawing than other artists, they get a +1 bonus (for each para).
-> Gift Bonus: If a para from a non-participant gets drawn, every (affected) artist gets a +1 bonus.
Companions, Caretakers and humanoid AUs earn half* of the values artwork of a Paralogos would earn.
Pixelart also earns half* of the values of fullsized artworks.
(*rounding up)
Literature Collaborations
If the word amount of each collaborator is listed, ink is calculated based on those.
If not, we assume every collaborator wrote equal amounts.
Tiers are shared - meaning if they wrote about a Paralogos from one of them, it counts as Tier 2 for both (even if technically it'd be a gift for one of them).
Since it's a collab, collaborators don't get additional Tier 1 ink if their Paralogos is mentioned in their own collab.
Examples:
a) 4 artists with 4 shaded fullbody paras (1 for each)
A did the sketching
B did the lining
C did the flat color
D did the shading
A = 4*2 = 8
B = 4*2 = 8
C = 4*2 = 8
D = 4*2 = 8
b) 2 artists with 2 shaded busts (one each)
A did sketching & lining
B did coloring & shading
A = 2*2 + 2*2 = 8
B = 2*1 + 2*1 = 4
c) 4 artists with 6 shaded fullbody paras (1 for each, +1 for B&C)
A did the sketching
B did the lining
C did the flat color
D did the shading
A = 6*2 + 1(loner) = 13
B = 6*2 = 12
C = 6*2 = 12
D = 6*2 + 1(loner) = 13
d) The Admin Collab! (
)
3 artists with 6 flatcolored fulbodies + simpleBG
Mouse did the sketching
Taming did the lining & simpleBG
Speedy did the coloring
M owns 2 paras
T owns 1 paras
S owns 2 paras
Mewhaku (not participating) owns 1 para
M = 6*2 + 1(gift) = 13
T = 6*2 + 1(gift) + 1(loner) + 2(simpleBG) = 16
S = 6*2 + 1(gift) = 13
