Support Section

Janna is my favorite support champion because you can really feel the help you do when you save somebody by throwing tornado at enemies chasing, or by standing around giving mana, defence, lifesteal, spell vamp..etc

How to be a support: Leave your laning partner take the Cs (creep score) to feed him, BUT, WILL I FALL BEHING IF I DONT KILL MINIONS? you will have masteries and items wich will keep you ahead in gold. Also after you go back and buy if you have some spare gold less than 300 spend them all in wards and position them around how it says in the warding section above. All your mana will be used for shielding your laning partner and Initiating fights or disengaging, do not farm. My support build is very tanky aswell, so you have a very good survival throughout the game.
Dont use your howling wind to farm, it's a waste of mana, leave the minions for the carry! use it only to chase or to escape from a gank.

Positoning: Try to lane at bot with a range, or somebody who can carry, while your adc farms you can harrass and give pressence dont just stay in the bush like below, you can also put a ward to see in their bush. For example:

Other item options:If you're laning with somebody who doesn't need mana like Mordekaiser dont buy Mana Manipulator , just leave it for later.


Zeke's herald

Zeke's herald
Buy this instead of Will of the Ancients if most of your team is AD, This will be really helpfull, that way they wont have to focus on life steal and can just focus on damage.

___________________________________________________________________________________________


Abyssal scepter


If most of your team is ap and the other team is stacking magic resist buy this item, it will lower them 20 magic resist.

___________________________________________________________________________________________


Talisman of ascencion

Talisman of ascencion
This item important for its passive that gives 20% cooldown, mana regen and it has a speed buff active wich can be used to escape or to chase enemies. Also everytime you see a minion die near you, you gain +4 gold.

Locket of the iron solari


This gives 15 health regen. to close champions and it actives gives 50 and 10+ level defence it maxed 230 defence, i dont buy this because i dont think it is of much help, but if you like this items buy it.





Quint of Fortitude : This will make you very tanky early game, it will be very hard to take you down.


Glyph of Clarity : Ahh.. the much needed mana on Janna, this is very necessary.


Seal of Warding : Magic resist to avoid the harrass from ability champions.


Mark of Resilience : People will start to think you are more tank than support and will stop attacking you, this defence will fit in well.

Quint of Avarice : If you are going for a more expensive build get this runes.

Quint of Swiftness : With these runes you can get back faster to your lane from warding or buying.

What to do in Teamfights

In teamfights you will be very usefull, if not the most usefull player, try to keep a safe distance, you will be targeted first because you have ALOT of damage output on tornados Howling Gale. Shield Eye of the Storm your carry for that AD and damage absorb,throw tornados to fly away your enemies while your teammates damage them, if things get bad, flash in or if you're close, walk in the middle and use Monsoon, heal and turn the match around, it is very tricky to get a good position to Monsoon, it depends of experience and practice.

What not to do in teamfights

You should never be in the middle of a teamfight, keep a safe distance between enemies, on this picture it shows where not to be, always let the tank go in first and shield the one that's geting focused.



If you get in the middle of a teamfight and they target you, use Monsoon shield your self and leave as fast as you can, and if they deside to chase you use your Howling Gale or your Zephyr to slow them down. Or if you have Zhonya's Hourglass already use its active and become inmune to everything for a short period of time, this little time can really make a difference of who lives and die. In the next picture i get targeted and run away. XDD
