Thundering Arc is the Skywarden's path 2 tier 2 upgrade in Bloons TD 6. This upgrade switches the behavior of Skywarden's arrows, which now arrive instantly to their target (like a shot from a Sniper Monkey) and they explode on contact, creating an 8-radius blast that deals 1 damage with 4 pierce, and gains +0.5 pierce and +1 blast radius for every 10 units travelled. Additionally, the Skywarden ignores obstacles and gains the Set Target option (positioned before Strong), which can target any location within range.

Thundering Arc is usually an improvement due to the nearly instantaneous shots and ignorance of obstacles, as well as improved pierce when shooting targets from long distances. However, the upgrade can sometimes be a downgrade due to the reduced effectiveness on straight lines. Position this Skywarden at a location that maximizes coverage instead of straight lines.
