This line of nanos is required casting for your Engineer pet. It's actually more effective in the offense category than the Divert Energy to Offense trimmer, but can be combined with it (and its damage bonuses) for even more offensive capabilities. Combine these two with a high Qlevel Positive AGG/DEF trimmer (VERY important trimmer, makes the bot attack much faster) and a weapon enhancement or energy spike buff and you've turned an otherwise mediocre bot into a good damage dealer. Use engineer AC buffs on your bot to override the ACs lost by the divert to offense trimmer.

^ The tactics work. I haven't utilitized the aforementioned above techniques until lvl 180 (!). Also do not forget to use a (Trimmer - Increase Aggressiveness), which makes your bot attack faster. The craft guide can be found at anarchyarcanum.com at the time of this writing

Trimmer - Increase Aggressiveness is a taunt trimmer, not attack speed adder. Positive aggressive-defensive increases attack speed.

Great nano for increasing bot damage
