The normal values probably because all it does is adds a power of the knight to each piece.
What are the point values for the pieces in XXL chess?

Depend of a lot of factors: if you find yourself in the opening, middle game or endegame, mobility, forwardness, distance, colorboundness, capture etc. Besides the value of pieces its a bit diferent respect to other variants due the size of the board.
- Knight : 2-2.5 points only can move on 8 squares, short range atack only works as suport.
- Camel : 1.75 to 2.25 Colorboundness, medium mobility (8 jumps ) but its only works as a support and defense piece (in endgame its value is less)
- Bishop : 3.5-3.75 Colorboundness, mobility 25 (in average game 15-20) large range atack.
- rook : 5.25 very useful in the opening (support for pawn promotion) Mobility 26, large range atack
- General : 4.75 to 5.25 (endgames) mobility 16, short range, the best king's best defender and support of pawns, its value increases when there are fewer pieces.
- hawk : 7.25-7.75 mobilitity 33, large range, very very tricky piece and versatile (both movements complement each other very well) and the best enemy of the kings.
- Elephant 8.5 mobility 34, large range, works better in endgames or middle game with there are few pieces, usually needs a partner.
- queen 9.5-10 mobility 51, large range atack, easy double attacks, don´t needs an explanation.
- Amazon 12-12.5 in endames mobility 59, vulnerable to camel atack, So OP, is deadly to kings.

Dababa: color-blinded,mobility 4, bad at escorting and blocking.
Knightrider: Mobility long, good at far away attack,vulnerable to pawn chains.
Chancellor: mobility 34, range,good at pawn destroying,bad at surprise attack.
Archbishop: mobility 33,range,good at inner fortress attacking,vulnerable to Amazon.
