Overview
This hero has a trickier gameplay than before because of the passive (conductor), but it is easier to play with this hero right now using 1-2-3 skill combo. The ultimate skill of this hero is better than before, you can cast it through the ground, it means it has a larger range than before.
Strengths
It has a lot of AoE skill because the ultimate doesn't need a passive to make it splashed, before it needs a passive to make it splash. You can use this hero's ultimate right now for facechecking (checking the bush), because you can cast it right now through the ground, the Eudora before needs to cast it through an enemy only.
Weaknesses
The weakness of this hero is the assassins of the enemy, but the meta right now is utility or tanky heroes, so she might doesn't have a weakness on a current patch. In addition, she might be weaker against the assassins because almost all of the assassins could dodge her skills, not enough to finish or burst down the assassins of the enemy.
Burst
Arcane boots for magic penetration (burst). Lightning truncheon is for the early damage, it helps you to burst a marksman, assassin, or mage enemy in early game. Glowing wand is for extra burn, and it will give you an advantage if the enemy has a healer or regen heroes. Build a holy crystal to amplify her burst in mid game. Blood wings for extra shield because Eudora is squishy, you must buy it because it is the second-highest magic power item, and it will help the holy crystal's passive. And build a divine glaive for you to finish or burst down an enemy even in late game, because in the late game, most of the enemy has a defensive item. The sequence of these items may vary, boots then glowing wand if your enemies has a healer or regen heroes, maximize the anti-heal effect as soon as possible (then build the lightning truncheon after glowing wand). In addition, build the blood wings if you want to survive in a mid-game, then build the divine glaive if you don't have enough gold for holy crystal and you want to burst an enemy as soon as possible.
For Tanky Enemies
Arcane boots for magic penetration (burst). Lightning truncheon is for the early damage, it helps you to burst a marksman, assassin, or mage enemy in early game. Glowing wand is for extra burn, and it will give you an advantage if the enemy has a healer or regen heroes. Build a genius wand for you to be a genius (just kidding!), it is for continuous damage if your enemies has a lot of utility or tanky heroes. Then, build a wishing lantern for high hp enemies. And build a holy crystal to amplify your magic power (building a divine glaive is optional if you doesn't have enough gold in late game).
Cooldown Reduction
Use this build to gain a 40 percent cooldown reduction in late game (adding a magic potion). Build a normal boots in early game and prioritize the elegant gem in clock of destiny for you to maximize the early survival in a game (after buying an elegant gem, proceed to buy your magic boots for cdr). Buy a glowing wand for healers or regen heroes of your enemy, if they doesn't have any, you should buy a lightning truncheon instead for burst and cdr. Then, genius wand for the early magic pen. After that, you could buy the clock of destiny for you to have another 10 percent cdr. In your fifth item, it should be a wishing lantern for you to have a 30 or 40 percent cdr (it could be 40 percent cdr if you replace the glowing wand for lightning truncheon). And for your 6th item, it could be divine glaive for late game magic pen (holy crystal is optional if you have a lot of gold in game). Lastly, buy a magic potion if didn't replace the glowing wand because you need to accomodate the 40 percent cdr (if you already have a 40 percent cdr, buy a rock potion instead for you to have an extra defense).
Finisher
Assassin emblem is much better than a mage emblem in terms of damage, you could rotate asap because it has a +3 percent movement speed, and for the cooldown reduction, you can gain it from items (the 5 percent cooldown from the mage emblem doesn't matter). Rupture is for more adaptive pen. The bargain hunter is for you to build the core items of Eudora faster (weapons master is optional because it gives a lot of attributes, you could use it if you know the trick to farm or gain a lot of gold in game). And lethal ignition for bursting an enemy or use it if you know the trick on "small trade", like using it again and again after cooldown (temporal reign is optional because if you are confident enough on Eudora's skills, this emblem talent could help you to make a lot of flashy plays).

Battle Spell
Flicker is the appropriate spell for a mage for engaging or escaping. When engaging an enemy, they could use this spell (flicker) to surprise the enemy/ies. And they could use a flicker for escaping (eg. The Eudora failed to finish or burst down an enemy, it will have a turn of events, so flick out). Flick in! Flick out!
Play Safely! For VICTORY!
The tips and tricks for emblems are already instructed. And since the Eudora is a mage/finisher, you could use the bush to ambush an enemy (eg. you have a core assassin enemy, check their buff timers, and ambush them from a bush), always check your minimap for your map awareness. Eudora is squishy and doesn't have a dash or blink skills, so don't do a duel (1v1) if it is not a surprise attack or ambush, help your teammates from behind. Play safely! For VICTORY!
Best With Grock
100% co-op win rate
She needs a tanky roam that is aggressive, too (Hilda, Minotaur, and Chip are also fit for her gameplay).
Watch Out For Cecilion
100% counter win rate
Since Cecilion is a late game hero, Eudora can bully him in early game by poking.
