Sir Oofie Build GuideUpdated March 2026  ·  v1.0.64
Melee / TankArmor Scaling
The best Sir Oofie build in Megabonk stacks Armor Tome and Thorns Tome, using the Reinforced passive to convert every level into an Armor gain and Spiky Shield to convert that Armor into Thorns damage.

Sir Oofie is one of the two default starting characters. His Reinforced passive gives +1% Armor per level. He starts with Max HP 150 (+50) and Armor 17% (+17%) above baseline. The wiki confirms strong synergy with Thorns Tome and items that reward sustained contact.

The Aegis wiki explicitly states that Sir Oofie gains enough Armor from his passive to give the same Thorns as Athena's passive with a single Spiky Shield, and surpasses Athena significantly with two. The Tank Oofie wiki build (4 stars) targets 70% Lifesteal by the first stage boss.

How to Build Sir Oofie in Megabonk

Sword is the primary weapon. Armor Tome raises the stat that Reinforced also builds every level. Thorns Tome is wiki-confirmed as Sir Oofie's core synergy. Spiky Shield converts Armor into Thorns, and the Aegis wiki confirms Sir Oofie surpasses Athena's Thorns with just two Spiky Shields. Leeching Crystal (Kevin) provides lifesteal per the Tank Oofie wiki build.

The Tank Oofie wiki build (4 stars) pushes lifesteal to 70% by stage 1 boss and 100% by stage 2, with 60% or more Armor. Bloody Tome and Leeching Crystal (Kevin) are the lifesteal route. Aegis provides the defensive weapon layer. Any weapon that scales with Projectile Count is recommended by the build author, especially multi-hitting weapons like Aura, Katana, and Black Hole.

Three weapons, three tomes. Sword handles melee, Aegis provides the block layer, Chunkers covers nearby AoE to compensate for Sword's short range per the wiki's recommendation. Armor Tome first to compound with the passive. Thorns Tome second. Forgiving because Sir Oofie's 50 extra Max HP and 17% starting Armor make early mistakes survivable.

How to Play Sir Oofie in Megabonk

Spiky Shield converts Armor into Thorns

The Aegis wiki page confirms Sir Oofie's Armor scaling from the Reinforced passive gives the same Thorns as Athena's passive with just one Spiky Shield, and surpasses Athena significantly with a second. Every level of Reinforced gives +1% Armor and that Armor feeds directly into Spiky Shield's Thorns output.

Thorns Tome is wiki-confirmed for Sir Oofie

The Sir Oofie wiki page specifically names Thorns Tome as a strong synergy alongside items that reward sustained contact. More Thorns means enemies take more damage just for hitting Sir Oofie, which compounds with Spiky Shield and Cactus as the enemy group grows.

Armor Tome stacks with the passive

Sir Oofie gains +1% Armor per level from the Reinforced passive AND more Armor from Armor Tome. Both stack together. Armor caps around 94% per the Armor Tome wiki, but the combined scaling from passive and tome reaches high Armor much faster than other characters.

Pair with AoE weapons for short melee range

The Sir Oofie wiki confirms short melee range is his weakness and recommends pairing with crowd-control or AoE sources to compensate. Aegis, Aura, and Chunkers all provide AoE coverage while Sir Oofie stays in close range where his Thorns can deal damage to anything that hits him.

Best Items for Sir Oofie

All three items feed Sir Oofie's Armor and Thorns scaling. Spiky Shield is confirmed by the Aegis wiki as Sir Oofie-specific. Leeching Crystal is from the Tank Oofie wiki build (4 stars).

Spiky Shield
Spiky Shield
Gives Thorns based on current Armor. The Aegis wiki explicitly confirms Sir Oofie equals Athena's Thorns damage with one Spiky Shield, and surpasses her with two, because his Reinforced passive stacks Armor every level. The single most Sir Oofie-specific item in the game.
Item Leeching Crystal
Leeching Crystal
Core lifesteal item. Three combine into Kevin. The Tank Oofie wiki build (4 stars) targets 70% Lifesteal by stage 1 boss. Kevin's lifesteal keeps Sir Oofie alive while his Thorns damage slowly destroys adjacent enemies.
Cactus
Cactus
Procs Thorns spikes on every hit taken. Compounds with Spiky Shield's armor-based Thorns and Thorns Tome. The more enemies attack Sir Oofie simultaneously, the more Cactus procs per second.

How Good is Sir Oofie in Megabonk?

Sir Oofie is one of the most beginner-friendly characters in Megabonk. His high starting HP and Armor make early runs forgiving, and his passive compounds with Armor Tome to reach very high Armor values. In the right build with Spiky Shield and Thorns Tome he becomes extremely tanky while dealing meaningful Thorns damage to every enemy that attacks him. His weakness is offensive output: Sword is a straightforward melee weapon with no special mechanics, so he relies on sustained contact and Thorns to deal damage rather than burst.
