Things are indeed messed up though, it has nothing to do with full CON. You can check it out for yourself here: https://tos.neet.tv/zones - new maps are Khonot Forest and below.
If you click the mobs on each map, you can see every single monster in the new maps has at least twice as much mdef as they do pdef, with some reaching much higher.
Some examples:
https://tos.neet.tv/npcs/58475 - 462 PDEF / 1142 MDEF
https://tos.neet.tv/npcs/58433 - 316 PDEF / 1948 MDEF
https://tos.neet.tv/npcs/58490 - 352 PDEF / 1430 MDEF
https://tos.neet.tv/npcs/58487 - 345 PDEF / 1418 MDEF
And none of these mobs are even level 300, meaning you canāt even use any new gear at that point. If you wanna delve into lv300+ mobs:
https://tos.neet.tv/npcs/58553 - 446 PDEF / 2404 MDEF
https://tos.neet.tv/npcs/58550 - 444 PDEF / 2334 MDEF
https://tos.neet.tv/npcs/58554 - 519 PDEF / 1334 MDEF
https://tos.neet.tv/npcs/58549 - 446 PDEF / 1333 MDEF
https://tos.neet.tv/npcs/58551 - 400 PDEF / 2643 MDEF
https://tos.neet.tv/npcs/58450 - 522 PDEF / 1343 MDEF
https://tos.neet.tv/npcs/58446 - 523 PDEF / 1310 MDEF
https://tos.neet.tv/npcs/58566 - 403 PDEF / 2665 MDEF
https://tos.neet.tv/npcs/58556 - 1315 PDEF / 3118 MDEF (elite mob of which there are 4 on the map, one of the only mobs to ever break 1k pdef)
https://tos.neet.tv/npcs/58564 - 455 PDEF / 2410 MDEF
You can also calculate the damage you will do really easily having their mdef, Wizard has almost no damage multipliers.
(matk + skillatk - mdef) * 1.5 [if quickcast] * 1.01~2.00 [depending on attribute level]
So letās see, if you get the new 315 purple staff (~9m? crafting cost atm), +10ed it (21 480 472 silver with absolutely 0 failures), level 4 transed it (49.8m cost and 42 days of rolling every extra opening of saalus cubes), with Squire Weapon Maintenance buff on, as a level 330 full INT character youād reach aboutā¦ 2948~3068 matk depending on hat enchants.
If you want to know how much, say, your Frost Cloud will do against a 1400 or 2400 mdef mob then just plug in the numbers (assuming 100% attribute):
(2948 + 643 - 1400) * 1.5 * 2 = 6573.
(2948 + 643 - 2400) * 1.5 * 2 = 3573.
Same calc with level 10 dark theurgeās numbers, 1984:
(2948 + 1984 - 1400) * 1.5 * 2 = 10596.
(2948 + 1984 - 2400) * 1.5 * 2 = 7596.
Anyways, i hope the post wasnāt too long. Bottomline: Itās completely asinine to have mdef values this high, specially in comparison to pdef when there are no real ways to mitigate mdef (against at least 3 skills to my knowledge that nullify pdef entirely). Magicās only real multiplier is in the number of hits it tends to do, but that also results in MDEF applying to every single hit. Physical classes now have a myriad of multipliers through buffs and debuffs, along with high base damage-low hit count skills, to a point where high PDEF would hurt them a lot less.
