There are different ways to look at this as it pertains to a tactics mage. You have to consider many things. The playstyle in general. First of all, you can put away the thought of doing mass damage with a melee hit in general. Concussion blow was nerfed down and you will probably only get it off on your first assault. After that it is a rabbit chase. The bone harvester concept still has a little juice as well as a war fork mage. However here is something I would like to try.
A micro bush mage. With the last publish they fixed the nerve strike bug, now you should be able to nerve strike those that are casting or doing other forms of actions.
The following template is just an entry level. It gives the ability to nerve strike and riding swipe. Note that Nerve strike and riding swipe damage is tallied up with the level of Bushido, Parry and also anat, tacts, str bonus as well as Damage increase items are calculated for damage. Stating this I encourage others to join in and maybe we can cook up the best template to find the best damage mix.
Base Template
50 bush
90 tacts
120 swords
120 Magery
100 med
120 resist
120 eval
Update - I went on test center to do some test. This is some of my finding, just on using nerve strike on critters.
First of all there are 3 types of damages calculated in a nerve strike
1. Nerve strike direct damage - Based on Bushido skill. The higher the skill , the higher damage. Testing showed Parry had no effect in the damage where it was stated otherwise.
2. Base weapon damage - tactics, str bonus, anat, and di reduced by armor resist. Common melee damage.
3. Hit spell effect - This also is included.
Note: As far as hit spell effects, the best would be hit fireball. For some reason there is a bug with hit lightning which negates the direct damage as well as the base weapon damage.
Thus at times you will see 3 sets of damages off of one nerve strike. Combine this with a combo and you got yourself a good offensive mage. Other benefits is confedense and LS. Don't however count on evasion. With this and pots it should be a decent template and the ability to use other weapons to disarm,mortal and bleed.
