what does the Grail Reliqua do, should i have it i have 128 points left???????????

If you want better infantry than Men at Arms (and you have at least one unit of Grail Knights) then the Grail Pilgrims are pretty decent. If you're mainly cavalry and archers, and you don't care about infantry, then don't bother.

They're good for taking the charge of the enemy without being broken at the first turn with their Stubborness and 8 Ld. They're kind of a way to replace a swarm: they won't kill much, but they add numbers and can keep the enemy busy for a few turns. They're perhaps a bit expensive, but take them if you have enough points.

I myself don't take them. I'm like the kind of guy Arioch described, "mainly cavalry and archers".

They are vastly underestimated, they can tie up a unit with stubborn then you can use your knights to flank, its very reliable, you should definately use one. Its good for disposing of tough units like chaos chosen or temple guard.

Hope it helps
