After 8 years or so of waiting it's finally released lol.
The first batch was released today, the second batch is planned to be released about November
Clan Iorwerth - Melee and Slayer
- Morvran is a steely-eyed slayer master who requires at least 85 Slayer and 120 Combat.
- Hall of Fame: this is Movran's special assignment, sometimes offered while completing assignments for him. Kill ten bosses in a row, with debuffing crystals making each fight harder than the last.
- Rush of Blood: a weekly D&D in which you must survive for ten minutes, defeating as many waves of monsters as possible. There are four difficulty levels, with increasing entry requirements.
- Preferred assignments and assignment extension are both newly available from the Slayer Points Store.
- Crystal chest: just like the existing one, but with a new and improved drop table.
- An altar that allows prayer/curse switching, and imparts a combat buff.
Clan Trahaearn - Mining and Smithing
- Seren Stones are like ivy for miners. From level 89 Mining, you'll be able to chip away at them indefinitely for excellent XP rates.
- Corrupted ore: While mining the stones, there's a chance each swing to collect a piece of this stackable substance. It can be smelted in a furnace, giving a helping of Smithing XP.
- Gemstone rocks: with superior drop tables and drop rates.
Clan Cadarn - Ranged, Magic & Max Guild
- Max Guild Garden: accessible with at least one 99.
- Two skilling portals: found within the garden, these can be attuned to a selection of high-level skilling locations - one at your first 99, the other at 15 99s.
- Max Guild Tower: accessible once you're eligible for the max cape.
- PvM portal: within the tower which can be attuned to one of many high-level combat destinations.
- Throne of Fame: sit here once you're eligible to wear the completionist cape and enjoy an appropriately lofty vantage.
Clan Crwys - Farming and Woodcutting
- Elder tree patch: usable at 90 Farming.
- Spirit tree: if you can access two spirit trees already, speak to Glouron to unlock this third one.
City-Wide Activities
- Combat: train by fighting the elven warriors found around the city.
- Pickpocketing: from level 91 and up, Prifddinian elves can be pickpocketed continuously with one click. Once you're noticed, you'll become unable to pickpocket that elf, and after three strikes, you'll be unable to pickpocket any elves of that clan for 20 minutes.
- Crystal Implings: these rare critters occasionally appear in sectors where the Voice of Seren is active, and in Puro Puro. They require 95 Hunter to catch, and can yield valuable items: crystal tree seeds, triskelion parts, and more.
On top of that, there's a 'voice of serem' (which shows in the top left of your screen) which blesses a specific area for an hour (which gives XP boost in training skills within that section)
The update in November (planned) will introduce the other clans (Hefin, Meilyr, Ithell and Amlodd) which will focus on others skills.
The current XP rates is fairly high so I expect it will be nerfed at some point today or later and the drop rate of onyx from the gem mines seems quite high (certainly isn't rare as it's meant to be)
