OK just need some clarification: this one is regarding the ATTACK Mode spells

OK so let us say that the caster has Attack mode of +6 and MR of +4 so total casting bonus of +10

Now he wants to cast a Lightning Bolt at a target 40ft away that will cause 12 points of damage

The caster has to roll a D20 -2 (-12 for spell level, +10 casting = -2) and compares this to the Omni Table

--lets say he rolled a 12-2 resulting in a 10 which is a partial success so it will only do half damage of 6 points

--now the caster has to roll again to actually hit his intended target

------He uses his CR + Mode skill versus a DoD equal to the target’s DEX + Evade Skill to hit.

------He has a CR +2 and Attack mode+6 total +8 vs the targets Dex of +1 and Evade skill of +4 total +5

------So he is at a +8 - 5= +3 to his roll

------Now we have to take range into effect (The spell has a base range of 50ft) The target is beyond half effective range so it gets another -5 penalty

-----------So he is now at +3 -5= -2 final tally to his D20 roll on the Omni Table

-----------Lets say he rolls another 12 -2 resulting in a 10 which is another partial success so it will only do half damage bringing the final damage total down to 3 points

Am I missing something or am I doing this right?

Figure I will tackle this one mode at a time.
