Newly Found Build :) Need Critique!

I haven't done much testing since i've just recently thought of this build and used it only once in a 3v3 between Myself, Ignacio, Some pub, vs Maj, Undead-boy and Burnok (anyone ever heard of him? lvl 16 pub, he was pretty decent actually :S )

So i ran this on a Str - Death Knight to be precise since hes my go to for str heros

Off Skill - Fireward, good for farming, and 3v3 duels, even if only for a little while
(main this!!)

Deff Skill - Mana Flare, this is to mess with other peoples farming game early, and duels especially (off level this at start to lvl 3-4)

Misc Skill - Rejuvenation, seeing as this was a team game, i decided a heal would have been nice, seeing as i was a str tank, and helpful to allies aswell
(off level this AFTER Mana Flare is lvl 3-4)

Innate Skill - Mana regen, to help with the mana expense as this is fairly hefty on the Mana Side

Ultimate - Elemental Mastery, this was to help for farming without the cost of mana, as well as to punish opponents' AMS and opponents without Spell Resistance

The only counter i could see to this build would be kiting, and early Int users with Silent Night or high dmg spells, as well as its down fall in mana cost,

However i figured the kiting would be countered ish, with the use of rejuvenation and as for the weakness of low mana and weakness to high dmg spells, grabbing a quick Spiked Gloves and Crown of Ages early game is a quick fix to this,

Thoughts, opinions, Epic, PLEASE! rip this apart that includes anyone else who feels fit to
As im still learning and any help is wanted

slow moving hero without anti kite?
avatar destroys this build so fast it isn't even funny, this build wouldnt' even be playable against a hero with 600 range, they can blast your ward away from 600 with never getting hit.

basically your counter any ranged hero with stone or lightning orb...

he used this in a team game, and it is generally a team-game build. When looking at it like that, you would think someone on the team might get an endu aura item; if not, he could. Boots of speed on that hero make him pretty quick. Boots of speed with a slow orb make him unkiteable. Light orb does hurt the build; but Fire ward is really great for farming, especially in a 3v3 where creeps spawn faster. Rejuv can be cast on anyone, forcing the other team to focus fire well, and one of them must have a light orb; so... you cant really CC a main target; allowing that target to survive a bit longer.

I think this build is much better than charge gives it credit for. Granted, in a 1v1, it would be killed pretty easily by anyone who likes to kite; if you dont get endurance, and they get avatar... A lot of what-ifs. In a team game though, I think this is a great build; so props.

idk i still feel the build is still too mana intensive. getting absorb mana wouldn't be that bad either on this build

I almost never have mana problems with strength. I guess thats just the way I build them I suppose. Heck I think you can even run an immolation build on strength and do fine. Are you going the passive strength build route most of the time? Just know there is two routes you can go caster and passive you don't always have to be passive.

Yeah i clued into how much bait it is for a ranged kite, but i almost always get Cloak of the fox on all my build seeing as its a cheap Totomic set, (usually) sometimes i find its not nessecary. Boots i however always get due to a post a read some time ago, i forget where but imsofattest said "move speed wins games" and it hasn't let me down since

well absorb mana is also powerful pvp, which can make you more competetive early game when ints are gonna nuke you down

yeah i'd go absorb mana > flare. u can use absorb mana on creeps and allys(who mass mana) it also rlly screws with them builds that only carried enough mana to use thier farm skills.

Hmm sounds pretty solid actually, ill give it a shot

also if you get mana steal for your defensive you can get something better for your innate skill like flare it would help in team games and great for anti kite
