The Tupi Blackwood Archer is an archer with fewer hit points and ranged resistance while having a stronger attack. It has the same range as a Skirmisher since the Definitive Edition. Despite the weak hit points and ranged resistance, it has a devastating ranged attack with a quick rate of fire and also has the same multiplier as the Skirmisher versus heavy infantry.
For comparison, a Veteran Skirmisher deals 36 damage to heavy infantry for every 3 seconds in the Fortress Age without any upgrades, whereas a Tupi Blackwood Archer deals 76 damage to heavy infantry for every 3 seconds in the Commerce Age without any upgrades. However, this does not factor in the setup animation of the Tupi Blackwood Archers, which does not let players kite with them.
They also inflict superior melee damage than most archer type units (same melee damage as an Iron Troop) and cost only slightly more than a Crossbowman.
Upgrades native warriors to Legendary/Exalted (+50% hit points and attack)
The Legendary Native Warriors improvement is available in the Capitol for European civilizations and in the Town Center for Native American and Asian (as Exalted Natives) civilizations.
Tupi warriors wore little or no clothing when they went into battle, though often they would paint themselves red or black. They would not fight after dark, but dawn would bring the sound of their horns calling the warriors to fight. The Tupi primarily used bows, which they fired rapidly and with an accuracy that amazed the Europeans - mostly Portuguese, Spanish and Dutch - who encountered them. Fighting between family groups was commonplace among the Tupi, and they did not hesitate to add the European invaders to the list of their enemies.
