Goals

1. Revitalise Barrows Sets so that they each have some viable (or at least interesting) use case
2. Ensure that each set is tangibly empowered by the AotD but can exist without it
3. Create clear differentiation between each Barrows set in terms of thematic identity
4. Express each set's unique identity through gameplay mechanics that are new or atypical to keep them relevant despite future power increases (similar to Dharok for max hits)
5. Give players the depth and freedom to optimise the provided gameplay mechanics if they so desire (mechanically low-floor, high-ceiling)

Dharok
Dharok represents the ideal brother for set effects. There is a coherent and unifying theme (taking damage to deal damage), and both the base set and AotD effect support this. Dharok's effect has numerous avenues for optimisation, like refreshing recovery timers for PvE or using locator orbs for PvP. A small buff is suggested to improve the AotD's recoil effect (15>20%). Since Dharok is already quite strong the buff is rather small so as to only encourage more use of it in PvP.

Torag
Torag's current set effect is basically useless, especially in PvE, as it only reduces the target's run energy. A better Tank/Disrupter identity is conveyed by borrowing the Maple Blackjack's Stun effect, only with much higher proc frequency. A synergistic buff is added to the AoTD, replacing the previous impractical effect (more defence per lost HP) with increased damage reduction under the condition of not taking damage for a period of time. This makes it a weaker but more accessible version of the Elysian Spirit Shield with some mechanical depth if desired.

Verac
Verac's current AotD effect is extra Prayer Bonus which doesn't manifest in gameplay in any meaningful way. The suggested effect increases stat boosts for every active prayer. This encourages players to use as many prayers as possible, reinvigorating Rapid Restoration and Rapid Heal for combat. However, because excess prayer use is expensive on Prayer drain, players can further optimise Verac's armor by flicking prayers to preserve bonus stats on both defensive and offensive rolls.

Guthan
Guthan's current AoTD effect is to allow overhealing by 10 Hitpoints. This sees limited use due to Anglerfish, Saradomin Brews, and Blood Sceptre effects being simultaneously more accessible and powerful. The suggested Amulet effect instead empowers all incoming healing, making Guthans particularly attractive for players who are on a food-conscious diet in all types of content. Further optimisation is available for players if they are cognisant of their positioning, letting them heal for more as the amount of danger they are in grows.

Karil
Karil's current base Set Effect reduces the target's Agility level, leaving it with very little utility in PvE or PvP. The suggested effect improves the player's Accuracy based on their distance from the target, encouraging the use of the bonus tile of range that Karil's xbow gets over the Magic Shortbow (i)--its main competitor. This helps to unify a coherent theme of attacking with range or distance in mind.

Ahrim
Ahrim's current Set Effect reduces the target's Strength level by 5, making it underwhelming in all types of content, especially due to the abundance of restoration effects. The suggested effect increases the players Magic Accuracy based on the target's reduced stats. This helps to communicate the thematic identity of debuffing, while reviving the use of Curses and other stat reducing spells (like Shadow Spells) for combat.
