Invoker - kael

Invoker is one of my favourite hero in dota. He got total of 10 skills, which contains disabling skill , slowing skills , buff skills , invinsibility, AOE DPS skills , global skills , summoning skills , mana burn skills , eul's skills , and some other important skills and of course a three basic skills which is quas wex and exort, which each has their own special effect such as regeneration(Q), MS and AS(W), and of course damage (E). And i classify this hero as a killer-supporting type of hero for sure.

The combos :

Spellcaster Invoker

Equip : Arcane Boots (Because if you use magic this much, you'll need a pretty high mana) aghanim's sceptre (for lowering invoke cooldown and remove mana cost of invoke) Shiva (to slows aoe and increase your armor and mana) Guinsoo(this not only useful for supporting but when you fight enemy one by one it's really useful, trust me, cause it increase your invoker's mana and mana regeneration) Bloodstone(to increase your hp and mp and of course mana and hp regeneration for sure, and make sure you make this first after arcane boots, because you'll probably kill many units at the early game) Orchid (this is really useful equip, because it'll silent your enemy and do amplified damage to the enemy and i'll give a real mana regeneration for sure at 200% mana regen if i'm not wrong :p)

If you already have a aghanim's sceptre and have a pretty high level in quas wex and exort, you can use this set of skills for great AOE with lots of enemie's heroes :

Tornado >> EMP for burning their mana >> Meteor (use this first because it has a delay time before the meteor drop) then Defeaning blast >> Ice wall and then use ghost walk

With this set of skills, you can replace the needs for opening heroes such as raigor, leviathan, axe, centaur, enigma, etc.

Battletype Invoker

Equip : Power threads (to get an extra AS and use it at PT strength because it'll make your hp higher, and dont worry about the damage, you still have exort on your skills :) ) MKB (cause your attack to never miss/true strike and will have a chance to deal more damage) Desolator and cuirass (it'll give more armor reducing, plus the forge spirit which will spawn two at a times if you already have your quas and exort at level 4 and the forge spirits attack will do damage and armor reducing) Butterfly, and of course aghanim's sceptre to reduce invoke cooldown and remove manacost of invoke or if you don't need aghanim's sceptre that much, you can replace it by using tarrasque to increase your hp or shiva to increase your armor and aoe slowing for sure :)

Use forge spirit skill (EEQ) set the draft which contains Aclarity (WWE) and the stunning skill (QQQ : which i forgot what's the real name :p) and use aclarity to your self and make sure that you click E 3 times, not to draft it in your skills but to increase your hitting damage, and then use the stunning skill (QQQ) to your target, and make sure that your invoker and his forge spirit attack the target all at once so that the target can't even move his ass because the stunning skills which make the target gets ministunned everytime the target is attacked.

Thats my tips for invoker, and one important thing is, whatever invoker types you build, either spellcaster or battletype, you can always make the other invoker skills (which i don't write in each battletype or spellcaster) handy, cause each of invoker's skills are really amazing either for killing, escaping, disabling, cancelling channeling spells or teleport, and even for creeping :)
