Tip of the Spear

 is a side quest in.

Synopsis
The aggressive Wahaki tribe has been making business difficult for Master Kua of Crookspur Island. Kua asks the Watcher to assassinate the Wahaki leaders on Ori o Koīki.

Preface
This quest is received as an extension of the quest A Shrewd Proposition, and Of Like Minds.
 * Completing the quest by killing Ruāsare and the tribe leaders will earn the associated rewards for assisting the Crookspur slavers with the above two quests, however this will cause the mission Cruel Cargo to fail, and will displease the Queen in Fruitful Alliance.
 * Likewise, killing Master Kua and/or freeing the slaves on Crookspur for Cruel Cargo / Clearing Out Crookspur will fail this quest.

Walkthrough

 * When asked about it, Master Kua recommends that you approach the Wahaki tribe under the guise of friendship, but you can choose to accomplish the quest in one of two ways; subtle and direct.
 * See Ori o Koīki for different methods of entering the village, either peacefully or not.


 * Subtle
 * The subtle way involves reaching Ori o Koīki and sneaking in either by way of the side cliffs or by convincing the Wahaki you mean them no harm, then eliminating their leadership. Note that the items can be placed without the need of discretion, as there is no consequence for them "seeing" you place them.
 * Ruāsare, the ranga, can be eliminated by poisoning the koiki in her bedchambers. You can find a Infested Koīki at the base of the cliff to the west; it contains the wood-strangler wasp larvae and will choke the ranga. Once she's dead you can loot the unique spear Kahua Hozi from her body. Note that the ranga will only leave for her bedchambers in the evening.
 * Burapo can be killed by planting a bomb in the brazier in the shrine.
 * Tangara can be killed by tampering with his construct (you can convince him to let you do it with Metaphysics 5, Bluff 6, or Athletics 4, which will give you the command words). Then interact with it and use Metaphysics 6 to wipe its memory, giving you the ability to order it to kill Tangara.
 * Note that once you leave the sanctum, the tribe will become hostile. So should you choose to befriend the tribe instead of sneaking in, it might be a good idea to open the cliff side route (leading to Ruāsare's chambers) before killing the leaders, since it cannot be opened from the inside. This way you can then use the cliff side as an escape route, although combat with the entirety of the tribe does give good experience!
 * Direct
 * The direct way involves assaulting the tribe head-on. Gain access to the tribe either by the side cliffs, or by persuading Kipeha to let you in, and then eliminate the leaders.


 * Once the three leaders are dead, return to Crookspur and talk to Master Kua, completing the quest. Unfortunately he won't give you anything in reward, other than a "discount on his wares", and some experience.
