Changing the Bow

Thinking about changing the bow in order to bring the Atlatl back into play. Right now an Atlatl + Spear costs more than your starting 5 points, so the only time people are buying them is after they die. A Bow & Arrow, or Club & Sling are the most prevalent strategies, with the Bow's deadly animal immunity power making it extra appealing.

But from a game design perspective I don't like it. Beyond the pure immunity taking a lot of the fun out of it, it's also another exception that needs to be taught. And the bow itself coming with one arrow is funky too.

So I'm contemplating increasing the cost to 4 (arrows cost 2), removing the extra shot that comes with the bow, and getting rid of the immunity power. In exchange I'd make it +5 to hit, and keep the damage at 2. Here's what that would look like:

Weapon / Combo	Squirrel	Rabbit	Deer	Boar	Wolf	Bear
Club	38%	50%	74%	63%	38%	50%
Club First Hunt†	50%	63%	84%	74%	50%	63%
Sling	74%	84%	91%*	-	-	-
Spear	50%	63%	84%	74%	50%	-
Atlatl	63%	74%	91%	84%	63%	74%
Bow&Arrow	84%	91%	98%	90%*	71%*	83%*

† First Hunt is the +1 bonus a Club gets against an animal discovered this turn.

OK, clearly that has exchanged one imbalance for another. What if I made it +4 to hit? The sling is still valuable because it's cheaper and has unlimited shots, but let's see if that fixes any of the balance vs. the Atlatl...

Weapon / Combo	Squirrel	Rabbit	Deer	Boar	Wolf	Bear
Club	38%	50%	74%	63%	38%	50%
Club First Hunt†	50%	63%	84%	74%	50%	63%
Sling	74%	84%	91%*	-	-	-
Spear	50%	63%	84%	74%	50%	-
Atlatl	63%	74%	91%	84%	63%	74%
Bow&Arrow	74%	84%	95%	83%*	55%*	71%*

† First Hunt is the +1 bonus a Club gets against an animal discovered this turn.

Atlatl average kill odds: 75%, Bow&Arrow average kill odds: 77%.

Another factor to consider when making the comparison is that for half the animals the bow requires two shots, which means both extra movement (and not claiming the spot you were intending to), and the extra point cost of the arrows.

Update
Added the Club's First Hunt special power numbers.

Second Update
Corrected the hunting Deer with Bow & Arrow odds.
