Yup. Since thornmail doesnt proc items effects like liandry or rilay, you just have to buy more armor and magic pen.

item 3075 item 3068 item 3020 Plus flat Pen runes Oh and I've noticed (in very rare cases) if you build ap on your champ item 3001 is not a bad choice too since it amps magic damage by 10%. If you have innate sustain and ap ratios item 3146 can help alot too.

It depends mainly on the opponent's armor, and if they got %hp damages and armor pen. (without doing the maths, i'd say : red pen, yellow armor, blue armor, quints armor or pen)

UNIQUE: Reflects 15% of the physical damage taken (+ 25% bonus armor) from basic attacks and on-hit effects back to its source as magic damage

Now doing the maths.

Dr = real damages dealt by thornmail for one auto Att = incoming damages before reduction ArB = bonus armor you got Arb = base armor you got Rm = Magic resist from opponent Fmp = Flat Magic pen Pmp = Percent Magic pen Pap = Percent armor pen Fap = Flat armor pen AttR = real damages dealt by opponent in one auto Hp = your hp Nb = number of hits you can take Total = total damages dealt by thornmail before you are dead

Nb = Hp / AttR Attr = Att x (100 / (100 + Arb + ArB x (1-Pap) - Fap)) Nb = Hp x (100 + Arb + ArB x (1-Pap) - Fap) / (Att x 100) Dr = ( 0,15 x Att + 0,25 x ArB ) x (100/ (100+( Rm x (1 - Pmp) - Fmp ))

Total = Dr * Nb Total = Hp x (0,15 x Att + 0,25 x ArB) x (100 + Arb + ArB x (1-Pap) - Fap) / (Att x (100+ (Rm x (1-Pmp) -Fmp)

And now have fun optimizing this shit =D (hint : Multiple derivatives or enumation of solutions by a program).

If you want thornmail itself to deal more damage get magic pen and armor, like the others have said, but only armor items that don't slow attack speed so they can hurt themselves faster :P

item 3075 scales on your armor, so more armor will make it deal more damage.

Living longer will also deal more damage. So I'd advise building some items like item 3068 item 3143 before thornmail vs ad comps.

Thornmail doesn't give any health, you need health with your resistances to be tanky. Especially if they have any AP, I remember one shotting a nasus with Katarina like 25 minutues in because he had item 3110 item 3075 item 3047 . It did nothing for him.
