Predecessor Builds > Howitzer > Howitzer Mid: Maximized 642 Ability Power
Maximized Ability Power, Haste, Mana for consistent Ability use.
**Note: Omeda City website doesn't apply Oblivion Crown and Azure passives for Ability Power and Mana, had to calculate it myself.
Final Ability Power: 642 (From Oblivion Crown and Azure passives)
Final Ability Haste: 63 (From Orb passive)
Final CDR from Haste: 38.7% [ CDR % = {1-100/(100+Haste)} * 100 ]
Final Mana: 2,641 (From Orb and Azure passives)
If enemy comp is heavy healing (two or more of Khaimera, Rampage, Countess, Narbash), replace Orb with Tainted Sceptor. Still need Timewarp for CDR and Mana Regen, Azure for Mana and its passive gives ~83 Ability Power based the build's max mana. Will lose 520 Mana, and 39 Ability Power (lost from Orb and losing bonus Ability Power from Azure's passive on Orb's Mana), and 3.5% CDR when replacing Orb with Tainted Sceptor, but may really need TS's passive against excess healing that overpowers ally team's burst.
Need good spacing and well-placed mines to avoid purchasing Wraith Guards for movement speed passive. CDR from build may provide relief on using mines and ult more often for this. Replacing Orb with Wraith Guards will lose same stats as before but will only lose 29 Ability Power instead of 39. Will gain 15 Magic Pen. May not need more Magic Pen for Magic Pen's sake as high CDR gives better DPS. If enemy health is ~4,000, 15 Magic Pen only negates 600 effective health from resisting Ability Power. One or two rockets would make up for this effective health.
