Usually, its main use is for the early-game, although Hard Thorns crosspath can be useful in a few cases where there is a lack of external pierce buffs available. If lead-popping is unavailable then this upgrade can help make up for this limitation.


  • It is a useful early-game option for countering grouped bloons with Druids.
  • When paired with Thorn Swarm, the 1-1-0 Druid becomes an effective option against early grouped and spaced bloons.
  • However, with Obyn Greenfoot and the HotMagicIcon.png Hot Magic MK, this upgrade is only going to be really useful for popping Leads.
  • Set the targeting to Last to thin out as many of the stronger early-game bloons as possible.
  • Crosspath with Avatar of Wrath and support it with external camo detection to allow it to easily handle DDTs.

Version History[]

Hard Thorns has seen little change since release.

As an underused crosspath on this tower, Druid's Hard Thorns will now allow them to counter all of its weaknesses instead of just frozen targets. [...]
~ Ninja Kiwi
More needed crosspath reworking for the new 1xx Hard Thorns upgrade, as it now upgrades the druid from sharp to normal damage it doesn't make sense for the track brambles on 030 to not require this crosspath for lead popping. [...]
~ Ninja Kiwi
  • Nerf Hard Thorns is now required for Druid of the Jungle's aftervine to deal Normal damage.


Official artwork[]


  • Hard Thorns sort of resembles the Intense Magic upgrade for the Monkey Apprentice, as it improves pierce of the Apprentice's magical bolts, just like Hard Thorns improving pierce of each thorn.
