Speculation is it works like the random skills in Necromunda which would mean you can pick which skill category to roll in. So in your example you could either do a General skill or an Agility skill.
Another thing that I've noticed that I haven't seen anyone bring up yet; the standard skill categories that have been leaked all have 12 skills in them. Will this mean we get a D12 in the game and Strength and Agility categories are going to get some new skills?
The New General Skills:
1. Block 2. Dauntless 3. Dirty Player 4. Fend 5. Frenzy 6.Kick 7. Pro 8. Shadowing 9. Strip Ball 10. Sure Hands 11. Tackle 12. Wrestle
The New Mutation Skills:
1.Big Hand 2. Claw 3. Disturbing Presence 4. Extra Arms 5. Foul Appearance 6. Horns 7. Iron Hard Skin 8. Monstrous Mouth 9. Prehensile Tail 10. Tentacles 11. Two Heads 12. Very Long Legs
The New Passing Skills:
1. Accurate 2. Cannoneer 3. Cloud Burster 4 Dump Off. 5. Fumblerooskie 6. Hail Mary Pass 7. Leader 8. Nerves of Steel 9. On The Ball 10. Pass 11. Running Pass 12. Safe Pass
General used to have 14 skills in it, though Kick Off Return and Pass Block were merged into the one skill and moved into Passing skills in the guise of On The Ball. Iron Hard Skin and Monstrous Mouth were added to Mutations. Accurate was split into two adding Cannoneer, Cloud Burster, Fumblerooskie and Running Pass to Passing skills.
So any guesses whats going to be added to Strength and Agility if every category is getting 12 skills?
