[quote]Interestingly, it can't be purchased in the event store, and it's the only item with a very low drop rate...[/quote] While the Crossbow does not have an [i]individual[/i] entry for direct purchase from the Event store, it is listed as a potential reward when inspecting the Event Engram obtained by reaching Rank 2 on the Event Reward Track, suggesting that it is therefore a possible reward for purchasing the same Event Engram from the Event store. Unfortunately there is only one such Engram listed on the Reward Track and you are limited to purchasing a maximum of [b]four[/b] Engrams from the Event Store, so your chances of getting a drop outside of grinding the [b]Reclaim[/b] Activity will be limited during the current Event. Luckily the fact that the Crossbow will be a possible drop during all subsequent [b]Ash & Iron[/b] Events and will have an option to Focus for the drop during [b]Call to Arms[/b] means you won’t be out of luck if you don’t get one during the current Event.

Cause then they have fomo so players will play every trash event. It means they don't have to works as hard lol.
