There are a lot of recent changes in Oct that's not yet documented. You can read about it here: Oct 9 2023 Changelog

General Mechanics Change

• Regeneration speed is doubled for players (so that you will regen your HP/SP faster)

• Wedding clothing does not reduce movement speed.

Movement Speed

• Movement speed is capped at the value of 50 for both players and monsters

For reference:

• Normal player moves at speed 150
• Increase Agi lowers this value by 25
• Speed Potion lowers this value by 50
• Frenzy lowers this value by 25
• Bio3/Bio4 MVP moves at speed 100 if they are not buffed

Racial Resistances

• The maximum resistace to race, sub-race, size, boss and/or non-boss is 85%

Damage Reflect

• Reflecting damage triggers recalculation of stats.
• Reflect damage will work on boss monsters ONLY if damage to the player (or reflected damage) doesn't kill said player (if damage is less or equal to max HP).

WOE and Battlegrounds

• Team members in BG count as party members and guild members at the same time.
• Player sizes are all medium on WoE and BG maps
• Consumables and skill catalysts are not consumed in WoE (but you still need enough items to cast the skill)

Forged Equipment Changes

• Damage boosted from star crumbs in forged weapons increases from 5 dmg (not atk) to 30 dmg
• 3 star crumbs boosted from 40 flat damage (25 higher than normal 3 star crumbs) to 200 dmg, which is 140 higher than 3 star crumbs under the new change
• Weapons from a ranked forger has 100 bonus damage instead of 10 bonus damage

Status Changes

These are 3rd class status effects which Pre-renewal players may not be familiar with.

Status	Details
Burning	Deals fixed (1000 + 3% of MaxHP) damage every 3 seconds. Damage can not be reduced. Reduce 25% MDEF Burning Status now has a minimum duration of 3 seconds instead of 10 seconds. Duration is reduced by AGI, and slightly reduced by LUK Boss monsters are immune to Burning Burning damage is not considered as damage from player (counts as Kill Steal), and as such will reduce the experience given from the monster. If the last hit on a monster is from burning damage, it will not count towards a quest kill count.
Deep Sleep	Chat is disabled 2% of maximum HP/SP is recovered each second Damage from the next attack is amplified by 1.5x Duration is reduced by Base Level and INT Deep Sleep now has a minimum duration of 3 seconds instead of 5 seconds.
Frost	Reduce movement speed by 30% Reduce attack speed by 30% Reduce Hard Def by 30% (10% on monsters) Duration is reduced by VIT and DEX Frost now has a minimum duration of 3 seconds instead of 6 seconds.
Marsh of Abyss	Remove speed boosting skill effects and items Reduce movement speed by 10 to 50% Decrease AGI, DEX and FLEE Marsh of Abyss now has a minimum duration of 3 seconds instead of 5 seconds.
Stasis	Similar to silence where it seals usage of certain skills Duration is reduced by VIT and DEX Stasis now has a minimum duration of 3 seconds instead of 5 seconds.

Note: this is not a custom change for heRO but this is a very common game mechanics question- Identical autospell of the same skill and the same level do not stack. Only the highest percent is applied. For example, 2 Injustice Card in the same weapon will do nothing. The 5% chance to autocast Sonic Blow will not add to form 10%. In fact, the 2nd card is completely wasted.

General Homunculi Changes

• Homunculus can now critically hit
• Greatly reduce the RNG variation with an auto-reroll system on level up: for each stat that got no gains at all (+0), the game will automatically re-roll the odds to see if you can get a +1 to the stat. While it's possible that you still get a +0 in the end, at least you get a 2nd chance. Note that the reroll does not permit you to get a +2 or a +3 in a stat. This happens automatically whenever you level up. You will see the notification of the system kicking in within your chatbox.
• All Homunculus have their level up stat adjusted. In general, all homunculi is getting a stat buff in EVERY category. You will see the standard deviation to have greatly narrowed (aka: less likely to be screwed by RNG), while retaining the potential high ceiling in almost all cases.
• Homunculus has a hard cap of 95 hard def and 95 hard mdef
