If you take into account the sword modifier, you're doing 33% less damage than you could be doing because it's a large monster. So for starters, you'd either need to get weapon perfection or you'd need to switch to a carded axe with expert archer enchants.
If you're only doing 12k on monsters weak to fire using a 3x archer skeleton red twin, I suspect that you're not fire endowed and you're assuming that the red twin gives you fire elemental damage? Your damage seems low for a "I have elemental advantage" situation (I remember getting similar damage on neutral property monsters with an axe on medium sized monsters, so I'd be suffering same size penalties and no elemental bonus), and so it's probably that cannon balls are ammo (like bows) which override non-endow element, so you will need real fire endow rather than just the red twin edge to add the 75% damage against earth property monsters.
If you toss in the regular suite of party buffs (striking, odin's power, windmill rush), your damage should be much higher than where it's at now also. You can throw in porcellio armor, BSB combo (BSB should be better than a medal of honor given the base attack of a red twin), and boxes of resentment for an added damage bonus.
lol i know how to use an elemental converter. my damage is low because cart cannon is a low dmg spell as ive been saying this entire thread. and lol@ throw on a suite of buffs. do you think i walk around with my own personal team of priest, maestro, and sorc?
porcellio carded armor doesnt make a lick of dmg difference and you lose 10% hp buff from not using peco card (have thoroughly tested).
BSB is mainly for acid bomb dmg. it also isnt worth losing 20% of your SP and HP not using a variants shoe . its also 50million zeny and has gone as high as 70m in the last month. also 2 medal of honors are much better then BSB because its 10% magic attack AND attack +1000 hp and more sp.
Why did a topic about the new headgears become a huge argument about CC? Too many QQers 
because too many overgeared players that roll with a full team of buffers think a spell thats not balanced well for high lvls is overpowered since they themselves do good dmg with it.
Because of misunderstanding and/or people wanting their class to be as OP as possible, heaven forbid you'd have to actually invest playing time into the game with challenge.
^probably plays a ranger or priest. its attitudes like this that are the reason half of the classes in the game are either completely broken or have almost an entire spell tree of spells that dont work right (ie. taekwon, ninja, kagaro, gunslinger, mechanic, maestro, wanderer, minstrel, sura). My idea of a challenge isnt spending 10 minutes killing 1 monster. we call that a mindless grind. but hey since youre up for a challenge, how about you go level an axe mechanic to 150 without using TI
