No, you cannot reroll dice vs. Omega Leader if he has you TL'd. I know that. My question pertains to ships like Hobbie specifically: Can you still spend a Target Lock you have on Omega Leader, but reroll no dice? similar to how you can spend a stress token on Keyan Farlander to change 0 Focus results.
My thought is yes, as in how I have read it, spending the TL is not the modification that Omega Leader prevents, it is the rerolling of the dice.
