Actually, a rule update was planned for a number of range weapons. The summary cards for the following range weapons Common Bow, Crossbow, Long Bow are amended as follows: Special: When used on the move the number of dice rolled is 1.
The Sling summary card as released in the Horrific Horde expansion is correct.
The Reflex Bow summary card is amended as follows: The line - Do not collect Lore tokens - is deleted from the card.
This of course is because all units will collect Lore tokens when in Melee and range weapon units do not collect Lore tokens when doing ranged combat (per Battle Savvy Troops rules).
The Arbalest summary card released in the Beaded Brave expansion is the correct version and takes precedence over the Arbalest card found in the Hundred Years War expansion.
We have been playing with these changes for some time now and all these were planned to be part of an updated edition for BattleLore. Of course, you can start enjoying them right now by amending your current summary cards.
