Super Beast, like other previous DTCL clans, provides Super Beast generals with AD and AP based on the clans you have activated.
We've seen that Veigar from TFT Season 4 has permanent AP stacks in a match. The same goes for Super Beasts, although Super Beast champions only get permanent health stacks when they kill an enemy champion.
The Super Beast generals have full resistance and damage, so even though they only gather all the Super Beast generals, the team still has enough tanks and main damage dealers. Below is how to build Super Beast DTCL season 8 .
Super Beast General DTCL season 8

When a Super Beast champion kills another champion, they stop to celebrate and gain reputation points. Super Beast champions gain bonus AD and AP, +4 bonus maximum Health based on their overall reputation.
- 3 Super Beasts: 20% physical damage and 20 magic power
- 5 Super Beasts: 40% physical damage and 40 magic power
- 7 Super Beasts: 99% physical damage and 99 magic power
Nasus (Super Beast + Mascot)
- Ability: Nasus swings his staff at the target, dealing 200% physical damage and slowing their Attack Speed by 40% for 3 seconds.
Sylas (Super Beast + Outlaw)
- Ability: Sylas spins chains around himself, healing himself and dealing magic damage to nearby enemies.
Jinx (Super Trickster + Super Beast)
- Ability: Jinx fires a rocket at her target that explodes on impact, dealing magic damage to all nearby enemies and stunning them for 1/1.2/1.5 seconds.
Riven (Super Beast + Guardian + Fighter)
- Ability: Riven gains a health shield for 4 seconds and enhances her next 3 basic attacks with bonus magic damage. If Riven's attack target currently has less health than she does, her bonus magic damage is increased by 100%.
Vayne (Super Beast + Special Agent + Duelist)
- Ability: Vayne fires a bolt of lightning at the target, dealing 110/110/129% true damage.
Miss Fortune (Super Beast + Carry)
- Ability: Miss Fortune charges for 2 seconds, firing 8 bullets in a cone at the target, with each bullet dealing magic damage to the first target hit. Enemies hit in quick succession take magic damage for each bullet.
Let's say you only have Super Beast champions on the floor, if you win every round and take down many champions. By stage 6 you will have 400 health for each champion, with a team of 7 Super Beast champions, it is calculated that there will be 2800 health added to the team, equal to 3 Blood Armor.
It sounds appealing, but that's a calculation where you win completely and don't lose any rounds, which is quite difficult to happen. Still, the permanent health bonus is a reward that few DTCL factions have ever had.
Equipment for Super Beast generals season 8
Only Riven needs defensive items, and some of the items that are detrimental are Thunderbow, Fire Armor, and Titan's Grasp. Hand of Justice increases the damage of Riven's skills, but if you're just playing the Beast, you should only give Riven tank items. Miss Fortune and Sylas' items can be the same, so you can ask Sylas to carry MF's items.
Jinx's items are magic items so she can get items similar to MF, while Vayne deals true damage so she can use support items like Rageblade, Hurricane, Giant Slayer and can ask Nasus to hold them for her.

Early game
Keep 3 Super Beasts in the early game and add any other champion, it can be tank, damage dealer or support healer, control... Depending on what you need at that time. Level up to 5 early and continue adding other champions.

Mid game
The 5 Super Beast milestone is the milestone you need to reach in the mid-game, at this point you will find Vayne and start building items for her to become the main carry. Add a Duelist to increase her attack speed.

Endgame
By the end of the game, you can reach 7 Super Beasts if you have the boost from Tech Upgrade or have the Super Beast Seal. The Super Beast Seal can be built from Golden Shovel + Oversized Stick, so you can definitely boost it to this level if you have a golden shovel in hand.
If you don't have a Super Beast Seal, you can use 5 Super Beasts and add other champions to add more clans. This team will mainly be Vayne or Miss Fortune with Zed as a supporting character above.

If you can't find MF, you can use Vayne and Jinx as the main pair. However, you need to upgrade 1 of the two champions to 3 stars. The good thing is that this team's tank line is quite thick, so you don't have to worry about resistance.

If you only keep 3 or 5 Super Beasts, you can combine many other clans with Super Beast champions. You can use Miss Fortune and Vayne as the main damage dealers, Riven as a tank, and add other champions just to get the clan.
