What do you guys recommend as Talismans for Solder Eddie level 4?

At the moment i have GUARDIAN(red) and BOOST TALISMAN(yellow) providing good ATK and SPECIAL stats, but his two skills: BULLET TRACE & WAR-TORN deals random damage, which scales off both ATK and MAGIC - so should i instead aim to increase both his ATK and MAGIC stats equally, by replacing the GUARDIAN TALISMANS with etc. ASASIN TALISMANS(purple)? Or should i use only BOOST TALISMANS in all slots, half with +ATK and half with +MAGIC, and therefore also maximize the SPECIAL stat? In the description of the BULLET TRACE skill, it says that damage scales with SPECIAL STAT, whereas the WAR-TORN description says damage increases based on ones ATK and SPCEIAL stat. But at the same time the two skills are random damage skills, so should i aim at having equal ATK and MAGIC stats, or maybe a higher ATK stat because of the WAR-TORN skill that have increased damage based on ATK(and SPCEIAL)?

I hope some of you know.

Thanks!
