I'm not sure if anyone has already pointed this out.
While reading Patch Notes 10.23, I noticed something interesting regarding one item in particular.
BLOOMING EMPIRE: This item transforms into Watchful Wardstone once you've placed 20 Stealth Wards
IIRC, they have not made any changes to the following effect, shared by all starting support items once their quests are completed:
UNIQUE – WARD: Consumes a charge to place a Stealth Ward icon.png Stealth Ward at the target location (600 range), which reveals the surrounding area. Holds up to 4 charges which refill upon visiting the shop.
So if you haven't yet placed 20 Stealth Wards but you have the WARD effect on your completed support item, you can spam it while at the fountain.
I realized this was possible because, apparently, someone used this weird ability to spam wards at the fountain to set a record of 5,294 wards placed in a single ranked game.External link →
