KMST v1.2.495 - You & I (The Seed)

Really rough ring translations:

Note: All rings (unless otherwise indicated) have a prefix phrase that indicates that the effects of the rings are TEMPORARY. I also believe they have a chance of proccing, though they could also have actives. Idk. Ring names are all phonetic translations from their English counterparts so those were pretty simple.

Disclaimer: Probable mistakes.

리스트레인트 링 - Restraint Ring - Increases W/M ATT, but restricts movement

얼티메이덤 링 - Ultimatum Ring - User's W. ATT stat is set to 200 for the duration.

리밋 링 - Limit Ring - Maximum MP is set to 500 and boss damage is increased - Classes that do not use MP cannot use this skill.

헬스컷 링 - Health-cut Ring - Lowers maximum HP, raises Boss Damage.

마나컷 링 - Mana-cut Ring - Lowers maximum MP, raises Ignore PDR

듀라빌리티 링 - Durability Ring - Maximum HP is doubled

맥스크리 링 - Max Cri(t) Ring (Literally, MaxCri Ring)- Raises Max Crit damage

크리디펜스 링 - Cri(t) Defense Ring - Ignore PDR equal to your crit chance

크리쉬프트 링 - Cri(t) Shift Ring - Crit chance is substituted with your character's total %MainStat (I'm 90% sure this is what it means)

스텐스쉬프트 링 - Stance Shift Ring - Stance chance is substituted with your character's total %MainStat

링 오브 썸 - Ring of Thumb (?) - Increases your main stat by the total all stat your character has (could be totally wrong... definitely feels wrong)

레벨퍼프 - S/D/I/L 링 - Level Buff - S/D/I/L Ring - Increases STR/DEX/INT/LUK by your current level

웨폰퍼프 - S/D/I/L 링 - Weapon Buff - S/D/I/L Ring - STR/DEX/INT/LUK increased by your weapon's base ATT. - Probably an oversight, but the INT ring also increases based on ATT apparently (doesn't specify Magic Att)

스위프트 링 - Swift Ring - Increases attack speed.

오버패스 링 - Overpass Ring - Ignores W/M Def Up, Damage Reflect. Your (?) damage is increased for the duration.

실드스와프 링 - Shield Swap Ring - Instead of ignoring PDR, your defenses are applied to the enemy, replacing their own (I THINK this is the true translation. Could be very wrong.)

리플렉티브 링 - Reflective Ring - When attacked, you return the damage at an increased rate.

버든리프트 링 - Burden-lift Ring - (Doesn't have the "For a period of time" prefix) Chance to nullify all status effects.

리스크테이커 링 - Risk-taker Ring - Increases your W/M ATT. If you take damage, the buff disappears.

크라이시스 - H링 - Crisis - H Ring - If your HP falls below a certain amount, you gain defense(s?) and evasion for a period of time.

크라이시스 - M링 - Crisis - M Ring - If your MP falls below a certain amount, you gain defense(s?) and evasion for a period of time.

크라이시스 - HM링 - Crisis - HM Ring - If your HP AND MP fall below a certain amount, you gain W/M ATT - Classes that do not use MP cannot use this skill.

리커버스텐스 링 - Recover Stance Ring - After you recover from a status ailment, your stance% is increased.

리커버디펜스 링 - Recover Defense Ring - After you recover from a status ailment, your resistance to status ailments is increased.

타워인헨스 링 - Tower Enhance Ring - While in The Seed, when you clear a time-limited map, you gain (extra?) points (for the shop, I'm guessing).

I'd assume these could only be used inside The Seed.

Based on a Google Translation of what uni wrote on his site, I think the ring skills go up to Lv. 4 depending on how many of each ring you wear, and almost all the skills last for 4/6/8/10 seconds, with a cooldown of 300 seconds.
And the Ultimatum ring seems to set your range to 2,000,000, not set your ATK to 200 :f6:
