Discussion has come up as to how to handle a character that loses both eyes without retiring them from the warband. Here are some of the special rules I've come up with so far:
Blind character has -1 WS and 0 BS and -2 Initiative. Subtractions to skills are applied to the maximum skill for the character's race, so a Human can only have 5 WS and 4 Initiative maximum. The 0 BS does not mean he can not use missile weapons at all, he can still use the magical artifact the Bow of Seeking (in my opinion this would make him the awesomest blind character ever).
The blind character may not parry or cast spells if they require a spellbook, as he well always strikes last.
The blind character no longer gains benefits from the following skills: Step Aside, Wyrdstone Hunter, Strongman, Dodge, Scale Sheer Surfaces.
The blind character is immune to fear from fear causing models, although still suffers from fear causing spells, even if they act as regular fear (ie. the blind character would still have to take a fear test when charging the Necromancer who has cast Death Vision).
When the blind character is not within 6 inches of another friendly model it has to take an all alone test regardless of if there are enemies nearby. If he fails then he moves his normal movement in the direction of a scatter die. Reroll direct hit results from scatter die. If he walks into a wall his movement ends.
On the Serious Injuries chart treat another roll of Blind In One Eye as Dead. Treat Sold To The Pits as Captured. Treat Bitter Enmity as a Full Recovery unless there was another friendly model who within 6 inches of the blind character when the blind character was taken out of action, and only apply it's effect in battle if there is a friendly model within 6 inches of the blind character. The witness must have Line of Sight, survive the battle, and not be stunned when the blind character is taken out of action.
In the Scenario Wyrdstone Hunt the blind character may not pick up Wyrdstone shards. In Hidden Treasure he may not find the treasure. The blind character may roll an exploration die for the exploration chart, but the value is discounted from the amount of Wyrdstone found. He may roll to find rare items in the market as normal.
This has only covered vanilla rules, I would like to have more input on how to deal with unique attributes of other official and unofficial warbands, as well as how it would be adapted to newer rules or other house rules.
