This is a control vs scale matchup where Sion must manage wave control and avoid giving Ryze safe scaling windows.
Sion should not overextend to pressure early since Ryze scales well and has medium lane pressure but low early agency.
Focus on using your tankiness and engage tools to become a front-line threat in teamfights rather than forcing early kills.
Trading pattern
Use (E) slow to set up charged (Q) from protected angles, punishing Ryze when he steps up to cast (E).
Trade when (W) root is down to reduce his ability to lock you in for follow-up damage.
Avoid extended trades if your (W) shield is down or if (Q) is interrupted or dodged, as your threat drops significantly.
Danger windows
Respect (W) root combined with (E) and (Q) rotations when he has enough mana, as this is his main threat window.
Avoid committing when (W) root is available and mana is high, as he can punish your engages with crowd control and damage.
Be cautious when your (Q) is visible or missed, as you become vulnerable to Ryze's poke and follow-up spells.
Early game
Prioritize farming safely and stacking health with (W) to survive Ryze's poke and scale.
Avoid obvious (Q) charges in visible lane areas to prevent easy dodges and counter trades.
Use brush or fog angles to threaten charged (Q) and keep Ryze cautious about stepping forward.
Power spikes
At level 6, use (R) with clear pathing and team follow-up to force fights or return to lane with pressure; Ryze will try to sidestep or break your engage angle.
After your first tank item and with stacked (W), absorb space and threaten charged (Q) zones to become a reliable front line.
Respect Ryze's first mana/AP item spike by playing cautiously around his improved spell rotations and damage output.
Win conditions
Use wave control and fog/brush angles to land impactful charged (Q) knockups and build health stacks with (W).
Scale into a durable front line and look for long-range engages with (R) when your team is ready to follow up.
Deny Ryze safe farming by controlling the wave and punishing his step forward to cast (E) and (W), limiting his scaling potential.
